Antidepressive Agent

SynopsisIn a double reversal design the potency of thyrotropin releasing hormone (TRH) (500 μgintravenously) as a quick-acting antidepressive agent was evaluated. A first injection did seem to give rise to a very slight short-lasting effect, though this could not be ascertained clearly. There were no visible effects after a second injection. The thyroid stimulating hormone (TSH) response curve after TRH administration in the depressive patients group was blunted in comparison with that in a matched control group of normals.

AbstractReinke's oedema (RO) of the vocal folds is a condition of unknown aetiology. Cigarette smoking and vocal abuse may contribute to its development. Hypo thy roidism has been described as an aetiological factor but, to date, no controlled study has been published confirming this association. This prospective, controlled study compared thyroid function in 61 consecutive RO patients with an age and sex matched control group (n = 65) without laryngeal disease. Thyroid function was assessed by measuring serum thyroid stimulating hormone (TSH), free thyroxine (T4) and tri-iodothyronine (T3). Hypothyroidism was diagnosed when TSH was above normal with a T3 and T4 below the normal range.Four RO patients were hypothyroid at the time of diagnosis, compared to five of the control group. Six RO patients had past or present hypothyroidism compared to seven of the controls. One RO patient and two controls were euthyroid with marginally elevated TSH levels. Although the incidence of hypothyroidism in this group of Reinke's oedema patients is higher than expected in a normal population, it is similar to that in an age and sex matched control group, reflecting the prevalence of hypothyroidism in middle aged women.This study suggests that hypothyroidism is not an aetiological factor in the development of Reinke's oedema.

SynopsisA slow, continuous infusion of 1000μg TRH (thyrotropin releasing hormone) over a period of 4 h had a very faint and diffuse short-lasting beneficial effect on a group of 10 depressive patients. This was assessed in a double blind cross-over trial with placebo. The effect was of no therapeutic value. No difference was found between the depressive patients and a control group of normal subjects in TSH response, T3resin uptake, T4or free thyroxine index values as a consequence of the TRH infusion.

The Impact

Abstract In recognition of the GSA’s 75th Anniversary “Why Age Matters” we celebrate the 7th anniversary of the Gerofit dissemination initiative. Gerofit is an exercise and health promotion program for older Veterans that has been declared a Veterans Health Administration (VA) “Best Practice” and been disseminated to 17 VA’s across the country. Over 7000 Veterans have participated in Gerofit initiated programs and have reported robust outcomes including improved quality of life, physical and mental health, and high levels of satisfaction with the programs. For this symposium, we focus on newly acquired program outcomes that emphasize the importance of fitness as we age. The first paper compares hospitalization and emergency room visits between individuals participating in Gerofit for 12 months compared to a matched control group. The second paper describes four-year trajectories of physical performance to highlight the impact of becoming fit over expected normative trajectories. The third paper examines outcomes of a home-based geriatric walking clinic. The fourth paper describes the impact of exercise adherence on chronic pain. The fifth paper describes changes in medication utilization compared to a matched control group following 12-months of supervised exercise. These papers highlight the importance of fitness as a contributor to overall health during the aging process and celebrates that fitness matters, no matter when you start!

Group Survival

PURPOSE Recent studies indicate that BRCA1 breast and ovarian tumors may have an advantageous survival. In this population-based study, the survival of carriers of a mutated BRCA1 gene was investigated. PATIENTS AND METHODS The survival of 71 BRCA1-associated cancer patients (33 breast cancer, seven breast and ovarian cancer, and 31 ovarian cancer patients from 21 families with BRCA1 germline mutations) diagnosed after 1958 was compared with that of a population-based comparison group that consisted of all other invasive breast (n = 28,281) and ovarian (n = 7,011) cancers diagnosed during 1958 to 1995, as well as an age- and stage-matched control group. RESULTS No apparent survival advantage was found for BRCA1-associated breast cancers upon direct comparison. After adjustment for age and calendar year of diagnosis, survival was equal to or worse than that of the comparison group (hazards ratio [HR], 1.5; 95% confidence interval [CI], 0.9 to 2.4). In comparison with an age- and stage-matched control group, survival again appeared equal or worse (HR, 1.5; 95% CI, 0.6 to 3.7). For BRCA1-associated ovarian cancers, an initial survival advantage was noted that disappeared with time. Due to this time dependency, multivariate analyses cannot adequately be analyzed. Compared with the age- and stage-matched control group, survival again appeared equal or worse (HR, 1.2; 95% CI, 0.5 to 2.8). CONCLUSION The results suggest that survival for carriers of a BRCA1 mutation may be similar, or worse than, that for breast and ovarian cancer in general. This finding is in accordance with the adverse histopathologic features observed in BRCA1 tumors and underlines the need for surveillance in families that carry a BRCA1 mutation.

Significant Difference

We investigated the effects of nutrient intake timing on glycogen accumulation and its related signals in skeletal muscle after an exercise that did not induce large glycogen depletion. Male ICR mice ran on a treadmill at 25 m/min for 60 min under a fed condition. Mice were orally administered a solution containing 1.2 mg/g carbohydrate and 0.4 mg/g protein or water either immediately (early nutrient, EN) or 180 min (late nutrient, LN) after the exercise. Tissues were harvested at 30 min after the oral administration. No significant difference in blood glucose or plasma insulin concentrations was found between the EN and LN groups. The plantaris muscle glycogen concentration was significantly (p < 0.05) higher in the EN group—but not in the LN group—compared to the respective time-matched control group. Akt Ser473 phosphorylation was significantly higher in the EN group than in the time-matched control group (p < 0.01), while LN had no effect. Positive main effects of time were found for the phosphorylations in Akt substrate of 160 kDa (AS160) Thr642 (p < 0.05), 5'-AMP-activated protein kinase (AMPK) Thr172 (p < 0.01), and acetyl-CoA carboxylase Ser79 (p < 0.01); however, no effect of nutrient intake was found for these. We showed that delayed nutrient intake could not increase muscle glycogen after endurance exercise which did not induce large glycogen depletion. The results also suggest that post-exercise muscle glycogen accumulation after nutrient intake might be partly influenced by Akt activation. Meanwhile, increased AS160 and AMPK activation by post-exercise fasting might not lead to glycogen accumulation.
