Mental impairment and utilization of community services: a study of the elderly in a parish of Stockholm.

Before the implementation of the health care reform of 1992 (The Adel Reform), a study of the frequency of mental impairment of people in different residential and care services was conducted in a parish of Stockholm. All residents, 65 years or older, registered with Primary Care Centres, Geriatric Hospitals and other institutions were assessed with respect to cognitive function according to the seven stage "Global Deterioration Scale" (GDS). The age-specific frequencies of mental impairment were similar to prevalences reported in earlier studies. The frequency of cognitive dysfunction of non-institutionalized and institutionalized elderly was 42% and 52%, respectively, and higher for women than for men. There was considerable variation in the prevalence of cognitive dysfunction among subjects in different types of accommodation. For the different stages of mental impairment the average age was about the same. With increasing need and demand for services, and limited resources, these variations in cognitive dysfunction have important implications for structuring appropriate support systems in a population with a rapidly rising proportion of elderly people.

Medroxyprogesterone acetate supplementation diminishes the hypoestrogenic side effects of gonadotropin-releasing hormone agonist without changing its efficacy in endometriosis.

OBJECTIVE: To examine the effects of concomitant use of goserelin and medroxyprogesterone acetate (MPA) in the treatment of endometriosis. DESIGN: Thirty-eight women with laparoscopically confirmed endometriosis were treated with once-a-month s.c. injections of goserelin acetate 3.6 mg (Zoladex depot; Zeneca Pharmaceutics, Cheshire, United Kingdom) randomly combined with either MPA (100 mg daily; n = 19) or a placebo (one tablet daily; n = 19) in a double-blind trial. Symptoms and side effects were monitored for a treatment period of 6 months and a follow-up period of 6 months. Blood and urine samples were collected for the assessment of endocrine and biochemical parameters. A second-look laparoscopy was performed 6 months after the treatment in 29 women. RESULTS: The extent of endometriosis was diminished similarly in both treatment groups, as were pelvic symptoms. Fewer women in the MPA group had hot flushes and sweating at 3 and 6 months of treatment. Sex hormone-binding globulin decreased in the MPA group but not in the placebo group. Consequently, the E2 index (E2/SHBG X 100), reflecting the free fraction of E2, fell more in the placebo group than it did in the MPA group. The increased urinary excretion of calcium observed during placebo treatment was prevented by MPA. CONCLUSION: High-dose MPA combined with a GnRH agonist (GnRH-A) diminished some antiestrogenic effects of the agonist. A reduction in hypoestrogenic side effects and a possible bone-sparing effect can be regarded as beneficial, especially as the good effect of the GnRH-a on endometriotic implants and pelvic symptoms prevailed.

The short human figure drawing scale for evaluation of suspect cognitive dysfunction in old age.

Human figure drawings have been widely used to assess cognitive development in children. In the present study, free-hand human figure drawings were examined for 62 demented patients, and 60 normal elderly subjects. The drawings were scored for 53 body details using a method derived from work with children. A short scale of 15 details was developed by selecting body details with high item-total correlations which are simple to score even for untrained staff. This short scale had excellent interscorer and test-retest reliability and excellent concurrent validity as well. It correlated highly with the Mini-Mental State Examination, a commonly used screening test for dementia. The short scale discriminated demented and non-demented subjects and different levels of dementia severity as graded by the Clinical Dementia Rating Scale. However, no differences were observed between Alzheimer patients and patients with vascular dementia concerning presence of details in human figure drawings.

The perceived importance of appearance and oral function, comfort and health for severely demented persons rated by relatives, nursing staff and hospital dentists.

Dental health is an aspect of the quality of life. Oral treatment goals for, the severely demented and the benefits of oral treatment are complex issues. Severely demented people can neither express their wishes nor make rational decisions about oral care. Acting "in the best interests" of a demented person who refuses or does not understand the purpose of treatment depends on what perspective and treatment priorities the advocate has. For oral treatment of a demented person the advocate may be a relative, a member of the ward staff or a hospital dentist. In a structured interview, the relatives of demented patients in a Stockholm hospital and members of the nursing staff were asked to rate the importance of goals for dental care. These ratings were also recorded for hospital dentists. In this study there was agreement on the importance of freedom from oral pain and fear of aspiration. Nursing personnel gave priority to aspects of good care such as being able to chew and enjoy eating. Relatives were also concerned with social behaviour and communication such as fresh breath, normal speech, and normal appearance. The ratings by the hospital dentists were generally lower which might reflect professional awareness of the limitations of treatment success implied by cognitive impairment.

Reliability and validity of the Hierarchic Dementia Scale.

The aim of the study was to apply a method for measuring cognitive functioning in severely demented patients. Reliability and validity of the Hierarchic Dementia Scale (HDS) were tested. Fifty patients with dementia of the Alzheimer's type (DAT), multi-infarct dementia (MID), and dementia of mixed type (MIX) were studied. The interrater reliability was satisfactory as estimated by means of a kappa coefficient. The test retest reliability was rs = .96. The concurrent validity of the HDS, as measured by the correlation between the HDS and the MMSE, was rs = .86, and between the HDS and the CDR was rs = -.71. The results indicate that HDS is a useful and valid instrument for determination of the heterogeneous cognitive deficits in severe dementia.

Effect of growth hormone administration on human ovarian function and steroidogenic gene expression in granulosa-luteal cells.

OBJECTIVE: To study the effect of growth hormone (GH) in combination with an ultrashort-term gonadotropin-releasing hormone analogue/human menopausal gonadotropin (hMG)/human chorionic gonadotropin (hCG) regimen in ovarian hyperstimulation for in vitro fertilization (IVF). DESIGN: Prospective randomized placebo-controlled study. SETTING: University-based IVF program. PATIENTS: Fifty-four normally cycling women (27 control and 27 GH-treated) participated in this study. INTERVENTIONS: Human recombinant GH (24 IU)/placebo was given intramuscularly on alternate days starting on cycle day 4 until the day of last hMG injection. RESULTS: Serum estradiol (E2) and progesterone (P) concentrations were slightly lower in the GH group than in the placebo group on the day of hCG injection and 1 day thereafter (P < 0.01 to 0.001). Serum luteinizing hormone, follicle-stimulating hormone, prolactin, testosterone (T), and sex hormone-binding globulin did not differ between the groups. The follicular fluid (FF) concentration of T was higher in the GH group than in the placebo group (15.9 +/- 6.0 nmol/L versus 10.2 +/- 4.9 nmol/L, P < 0.005), and no differences were observed in the FF concentrations of E2, P, and insulin-like growth factor I between the groups. In granulosa cells isolated from patients who received GH treatment, the levels of 3 beta-hydroxysteroid dehydrogenase and aromatase messenger ribonucleic acid were significantly higher than in the patients receiving placebo. The number of hMG ampules needed for follicular development and the number of follicles and oocytes recovered were similar in both groups. CONCLUSIONS: These results indicate that GH administration modifies ovarian steroidogenic response to gonadotropins in IVF patients, suggesting a role for GH in the regulation of human ovarian function.

Laminin in the human embryo implantation: analogy to the invasion by malignant cells.

OBJECTIVE: To explore the possible similarities between the biochemical processes of embryo implantation and malignant invasion. DESIGN: The expression of a basement membrane (BM) glycoprotein laminin, a matrix binding cell surface receptor protein beta 1-integrin, and a BM collagen degrading metalloproteinase type IV collagenase, was studied in cultured human in vitro fertilized embryos. PATIENTS: Eight healthy women suffering from tubal infertility were participating in the IVF program in the Department of Obstetrics and Gynecology in University Hospital of Oulu. Twenty oocytes and 110 pre-embryos that were not transferred for the fertilizations were used in this study. MAIN OUTCOME MEASURES: Fibronectin, laminin, beta 1-integrin, and type IV collagenase immunoreactive proteins were studied in embryos by immunoperoxidase staining, and type IV collagen degrading activity was measured from the culture media of the embryos. RESULTS: Laminin and beta 1-integrin were expressed in the early human embryos before the time of implantation. Type IV collagen degrading activity and the 72 kd-type IV collagenase immunoreactive protein were expressed at the time of implantation. Laminin supported the expression of type IV collagenase. CONCLUSIONS: The expression of laminin, beta 1-integrin, and type IV collagenase in vitro are temporally in good correlation with the time of the implantation in vivo. Laminin and beta 1-integrin can relate to the attachment of the embryos to the uterine BM and type IV collagenase to the degradation of the BM collagen during the implantation. Laminin can augment the process locally.

Ectopic pregnancy and infertility following treatment of infertile couples: a follow-up of 929 cases.

A follow-up analysis was made of 929 infertile couples, with special attention paid to ectopic pregnancy. The conception rate was 46%, and 9% of the pregnancies were ectopic. Previous ectopic pregnancy, an industrial occupation and smoking reduced the fecundity and increased the risk of ectopic pregnancy. Tubal damage as a verified reason for infertility and its treatment also increased the risk of ectopic pregnancy. Stepwise logistic regression analysis showed the strongest association with ectopic pregnancy to exist in the case of women with a previous ectopic pregnancy (9.9-fold risk) rather than women with primary infertility. Treatment of tubal damage by salpingostomy entailed a 6.0-fold risk and treatment by other methods a 2.8-fold risk. Women working in industry had a 3.5-fold risk of ectopic pregnancy compared with those in other professions.

Gonadotropin pulsatility in a stimulated cycle: clomiphene citrate increases pulse amplitudes of both luteinizing hormone and follicle-stimulating hormone.

OBJECTIVE: To elucidate gonadotropin secretory patterns during ovarian hyperstimulation for in vitro fertilization. DESIGN: All volunteers who attended the unit during a period of 3 months were prospectively investigated. SETTING: Infertility unit of the University Central Hospital of Oulu. PARTICIPANTS: Normally menstruating tubal infertility patients (n = 8) and healthy women with ovulatory cycles (hospital personnel, n = 11). All patients finished the study. INTERVENTIONS: Clomiphene citrate (CC), 50 mg, was administered on cycle days 5 to 9 and 300 IU of pure follicle-stimulating hormone (FSH) on cycle day 7 and 150 IU on cycle day 8. MAIN OUTCOME MEASURES: Serum samples for luteinizing hormone (LH) and FSH measurements were collected at 10-minute intervals for 6 hours on cycle day 7 (effect of CC) and day 9 (effect of CC/FSH), and the data were analyzed with the Munro computer program. RESULTS: The number of LH peaks was identical in the controls and study subjects on cycle days 7 and 9, whereas the pulse amplitude (P less than 0.025) and the pulse area (P less than 0.01) were higher in the CC/FSH-treated patients. The increase in overall mean LH level during the hormone therapy was not significant. In the CC/FSH-treated women, a decreased number of FSH pulses (P less than 0.01) with increased amplitude (P less than 0.001) and pulse area (P less than 0.01) was found. Clomiphene citrate treatment increased the mean FSH level (control versus cycle day 7, P less than 0.05) which was further increased (cycle day 7 versus cycle day 9, P less than 0.05) by FSH administration on cycle days 7 to 8. Otherwise pure FSH was found to be unable to modify endogenous LH or FSH secretory patterns under these conditions. CONCLUSIONS: Clomiphene citrate increases the amplitudes of both LH and FSH pulses in the midfollicular phase of a stimulated cycle, an effect which is not influenced by pure FSH administration.

Insulin-like growth factor binding protein-1 and ovarian stimulation.

Serum concentrations of insulin-like growth factor binding protein-1 (IGFBP-1) were measured in 42 patients with tubal infertility undergoing two different regimens of ovarian stimulation for in-vitro fertilization. The first group comprised 24 women given a luteinizing hormone-releasing hormone agonist analogue (buserelin, LHRHa) on cycle days 1-4 followed by follicle-stimulating hormone and human menopausal gonadotrophin (LHRHa group). The second group of 18 women received clomiphene citrate and gonadotrophins (CC group). On the day of human chorionic gonadotrophin administration, the sum of follicular diameters (P less than 0.05) and the number of follicles punctured in the LHRHa group (P less than 0.01) were significantly higher than in the CC group. In spite of the greater number of follicles, the oestrogen levels were similar in both groups, but women in the LHRHa group had significantly higher serum IGFBP-1 concentrations during the last 5 days of stimulation. These results suggest that the stimulated preovulatory follicles may contribute to the elevation of serum IGFBP-1.

Regulation of steroid and steroid sulfate production and aromatase activity in cultured human granulosa-luteal cells.

The regulation of the production of steroids and steroid sulfates and the activity of aromatase in human luteinized granulosa cells were investigated. The cells were cultured for 48 h in the presence or absence of hCG and FSH. Basal production of pregnenolone (Pre, 0.3 +/- 0.03 ng/micrograms protein) and progesterone (P, 19.3 +/- 1.7 ng/micrograms protein) were high compared with that of other steroids beyond P in the steroidogenic pathway. The concentration of 17 alpha-hydroxyprogesterone (17-OHP) was lower 0.17 +/- 0.06 ng/micrograms and that of other steroids in the 4-ene and 5-ene pathways and steroid sulfates less than 0.05 ng/micrograms. Both hCG and FSH (100 ng/ml) stimulated the production of Pre and P 3- to 5-fold, but only minimal stimulation of other steroids and steroid sulfates was observed. Aromatase activity of granulosa-luteal cells was measured from the rate of formation of 3H2O from 1 beta-[3H]androstenedione (1 beta[3H]A) after exposing the cells to hCG, FSH or estradiol (E2) for 48 h. Basal aromatase activity was relatively low, but hCG and FSH stimulated aromatase 8- and 4-fold, respectively. The incubation of granulosa-luteal cells with E2 did not affect basal aromatase activity, but E2 augmented FSH-stimulated aromatase 1.4-fold (P less than 0.025). The results suggest that there is low 17 alpha-hydroxylase and steroid sulfokinase activity in human granulosa-luteal cells. Aromatase activity in these cells is regulated by both hCG and FSH, and intra-ovarian estrogens may regulate granulosa cell aromatase activity.

Short and long term effects of growth hormone on circulating levels of insulin-like growth factor-I (IGF-I), IGF-binding protein-1, and insulin: a placebo-controlled study.

The short and long term effects of GH on serum concentrations of insulin-like growth factor-I (IGF-I), IGF-binding protein-1 (IGFBP-1), and insulin were investigated in women participating in an in vitro fertilization program. In this placebo-controlled study, sterile saline (eight women) or 24 IU GH (eight women) were given im on alternate days, starting on cycle day 4, in combination with GnRH and human menopausal gonadotropin. IGFBP-1 levels decreased significantly during the first 4 h after GH administration, whereas no significant changes were seen in the placebo group. The concentrations of serum IGF-I and insulin did not change during 4 h after GH injection. During the 11-day follow-up period, serum levels of both IGF-I and insulin were significantly higher in GH-treated than in placebo-treated women. These results suggest that the serum concentration of IGFBP-1 is not completely GH independent. They also support the earlier findings that long term treatment with GH increases serum IGF-I and insulin levels.

Circadian and seasonal variation in human preovulatory follicular fluid melatonin concentration.

The concentrations of melatonin in 112 preovulatory follicular fluid (FF) samples obtained from 60 women undergoing in vitro fertilization and 27 patients at laparotomy during a spontaneous cycle were measured by RIA and compared with those in peripheral serum. The circadian and seasonal variations in FF melatonin were also analyzed. The FF melatonin concentrations in stimulated (mean +/- SEM, 61.9 +/- 6.4 pmol/L) and spontaneous cycles (98.1 +/- 8.9 pmol/L) were significantly higher (P less than 0.005) than those in peripheral serum (25.4 +/- 1.2 and 38.6 +/- 1.8 pmol/L, respectively), and in the stimulated cycles there was a positive correlation between them. The FF melatonin concentration in the morning (58.9 +/- 3.8 pmol/L) was significantly higher (P less than 0.005) than that in the daytime (23.2 +/- 0.8 pmol/L), but the morning concentrations did not differ between the light and the dark seasons of the year, whereas the daytime values were higher (P less than 0.005) during the dark season (27.1 +/- 2.1 pmol/L) than during the light season (21.1 +/- 2.1 pmol/L). The FF melatonin concentration did not correlate with follicular volume, and FF and serum melatonin concentrations showed no significant correlation with the serum concentrations of estradiol, progesterone, testosterone, or PRL. There were also no differences between FF melatonin concentrations in aspirates with or without an ovum. In summary, significant circadian and circannual variations in high FF melatonin concentrations were found, which suggest that melatonin could potentially interfere with the regulation of reproduction in humans at the follicular level.

Placebo-controlled comparison of hormonal and biochemical effects of danazol and high-dose medroxyprogesterone acetate.

The hormonal and biochemical effects of danazol (600 mg a day) and high-dose medroxyprogesterone acetate (MPA; 100 mg a day) were studied in a placebo-controlled, 6-month trial. Serum gonadotrophins and prolactin levels did not change during danazol and MPA treatments, whereas oestradiol and progesterone levels decreased significantly in relation to placebo without any difference between danazol and MPA. Both drugs significantly suppressed the sex hormone-binding globulin level (SHBG), and consequently, the free-androgen index (serum total testosterone nmol/l per SHBG nmol/l x 100) as compared with placebo, the effect of danazol being significantly stronger than that of MPA. Danazol, but not MPA, significantly increased serum aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT) and haemoglobin levels, and also thrombocyte counts, whereas MPA, but not danazol, increased the serum concentration of albumin in relation to placebo. Serum total bilirubin, conjugated bilirubin, gamma-glutamyl transferase, creatinine, alkaline phosphatase, sodium and potassium levels and leucocyte counts remained unchanged during both treatments. Danazol and high-dose MPA did not differ from each other in their ovarian and anterior pituitary effects, while the increase in androgenic activity induced by danazol was greater than that achieved with MPA. Danazol also had more biochemical effects than MPA. It interfered with the functions of the liver and the production of thrombocytes and haemoglobin, whereas MPA affected only albumin synthesis/release.

The ratios of serum bioactive/immunoreactive luteinizing hormone and follicle-stimulating hormone in various clinical conditions with increased and decreased gonadotropin secretion: reevaluation by a highly sensitive immunometric assay.

Serum bioactive and immunoreactive LH and FSH were measured in clinical conditions with increased or decreased gonadotropin secretion. Gonadotropin immunoreactivity was measured using a conventional RIA (I) and an ultrasensitive immunofluorometric method (F). Bioactive (B) LH was assessed by the mouse interstitial cells in vitro bioassay, and B-FSH using the immature rat granulosa cell assay. Acute GnRH stimulation of adult men (n = 6) increased LH levels measured by the different methods 4.3- to 5.3-fold. The B/I ratio of LH increased from 2.34 +/- 0.21 to 3.71 +/- 0.36 (mean +/- SEM) at 120 min (P less than 0.05), but no change was found in the B/F ratio. After ovariectomy of premenopausal women (n = 6), the LH levels increased in 1 week 4- to 6-fold, the B/I ratio from 1.85 +/- 0.22 to 2.59 +/- 0.24, and the B/F ratio from 1.78 +/- 0.22 to 2.90 +/- 0.30 (P less than 0.05 for both). In addition, the LH levels were measured during GnRH agonist treatment of ovarian carcinoma (n = 8), endometriosis (n = 8), and prostatic carcinoma after orchiectomy (n = 8). In the two former groups, serum B-LH decreased in 1 month to undetectable levels (less than 0.5 IU/L), and in the prostate cancer patients to 1.2 (0.8-1.9) IU/L (log mean and range of +/- SEM). The concomitant decline of I-LH was to 1.5-1.9 IU/L in the agonist-treated female patients, and that of F-LH to 0.10-0.15 IU/L; in the prostate cancer patients, respectively, these values were 7-8 and 0.3-0.7 IU/L. The B/I and B/F ratios during the agonist treatments could only be calculated in the prostate cancer patients (in the others, B-LH became undetectable). The B/I ratio decreased from 2.34 +/- 0.5 to 0.14 +/- 0.03 (P less than 0.01), but no suppression was found in the B/F ratio from a pretreatment value of 3.6 +/- 0.8. B-, I-, and F-FSH levels were measured in the GnRH agonist-treated orchiectomized prostate cancer patients. The pretreatment level of B-FSH was 154 (137-175), that of I-FSH was 38.0 (34.4-42.0), and that of F-FSH was 39.8 (35.3-44.9) IU/L. The B/I ratio of FSH was 3.76 +/- 0.49, and the B/F ratio was 3.53 +/- 0.59. The mean B-FSH level decreased during treatment by 87-93.5%, that of I-FSH by 98%, and that of F-FSH by 91.5% (P less than 0.01 for all).(ABSTRACT TRUNCATED AT 400 WORDS)

Endometriosis and infertility.

The relationship of endometriosis, the most common benign gynaecological disease during reproductive life, to infertility is generally ill understood. The association between infertility and minimal to mild endometriosis, when no anatomical defect is evident, may be explained by the following possible mechanisms: alternations in peritoneal fluid (macrophages - immunoglobulins, Interleukin-1, protease inhibitors, prostanoids, an ovum capture inhibitor), ovulatory dysfunctions (anovulation, LUF syndrome), luteal phase defect, disturbed implantation, and spontaneous abortion. These possibilities are discussed. The latest prospective controlled studies offer strong evidence that endometriosis per se is not a direct cause of infertility. On the other hand, the disease usually deteriorates if not treated, and therefore medical or surgical interventions are often needed when expectant treatment or other infertility therapies, e.g., ovulation induction, fail to result in pregnancy. Women with minimal to mild endometriosis only should be diagnosed as having unexplained infertility, which today may be treated by in vitro fertilization.

Endocrine responses to gonadotrophins after LHRH agonist administration on cycle days 1-4: prevention of premature luteinization.

A treatment regime comprising an intranasally administered luteinizing hormone-releasing hormone (LHRH) agonist analogue (buserelin) on cycle days 1-4, followed by gonadotrophin administration [follicle stimulating hormone (FSH)/human menopausal gonadotrophin (HMG)] resulted in identical oestradiol (E2) responses compared with the reference method using clomiphene citrate (CC) and gonadotrophins. Immediately after analogue administration (day 4), buserelin-treated women showed short-lived elevations in serum LH and progesterone concentrations, but in the later follicular phase, the serum LH concentration was lowered compared with the controls. None of the women treated with analogue displayed elevated serum LH or progesterone concentrations at the time of injection of human chorionic gonadotrophin. In the early luteal phase, these women had higher serum levels of progesterone and higher progesterone to E2 ratios than the controls, but the length of the luteal phase was slightly shortened. Hence, in hyperstimulated cycles, 4-day treatment with buserelin caused profound endocrinological changes: namely, short-term rescue of the corpus luteum, prevention of an endogenous LH rise and premature luteinization and increased progesterone production in the early luteal phase.
