The potential role of exercise in the alleviation of menstrual disorders and menopausal symptoms: a theoretical synthesis of recent research

Research in the last decade has advanced our understanding of menstrual disorders and menopause. Paralleling this research has been both a popular and a scholarly interest in the correlates and consequences of aerobic exercise. The purpose of this paper is to integrate these two domains on a theoretical and, when possible, an empirical level, and to discuss the potential benefits of exercise in the treatment of menstrual disorders and menopausal symptoms - specifically, dysmenorrhea, premenstrual syndrome, hot flashes, and osteoporosis.     

Psychological distress before and immediately after attendance at a male sub-fertility clinic.

Where treatment options are limited, the role of clinical consultation in providing information and support becomes more important. This study examines the immediate impact of medical consultation on male sub-fertility clinic attender's anxiety, depression, self-blame, information appraisal and perceptions of future fertility. Data were collected pre- and immediately post-consultation. Clinical information and consultation details were recorded. Results showed that anxiety levels were high before consultation. Following consultation anxiety and self-blame were both reduced while depression increased. Despite information about poor prognosis being given during consultation, participants remained overly optimistic about their chances of achieving a pregnancy. It appears that the consultation has a distinct psychological impact and possible mechanisms underlying this are discussed.     

Changes in metabolic rates and blood respiratory characteristics during pouch development of a marsupial, Macropus eugenii

Oxygen levels in the pouch of the tammar wallaby, Macropus eugenii, have been related to the metabolic rate of the young at pouch temperatures and the oxygen transport characteristics of its haemoglobin. Until 100 days of age, pouch young show mass-specific rates of oxygen consumption lower than predicted on the basis of body mass. This contrasts with data presented for laboratory mice. Oxygen levels in the pouch approximate atmospheric levels for the first 20 days and at times approaching pouch evacuation at 200 days. However, levels of around 17-18% occur at about the mid-point of pouch life. The oxygen-haemoglobin equilibrium curve shows a high P50 (up to 50 Torr at 36 degrees C) in the neonate, but after 2-3 weeks of age levels drop to those representative of the adult. Concentrations of 2,3-diphosphoglycerate in early pouch young are higher than in the adult animal and peak at around 30 mumol/g Hb. There is a significant decrease in the concentration of this compound with the age of the young.     

Effects of chelates and incubation media on platelet labeling with indium-111

We studied the effects of various [111In]chelates and incubation media on labeling efficiency (LE) and in vivo survival of platelets. High LE of human and rabbit platelets in plasma were obtained with [111In]tropolone and [111In]mercaptopyridine-N-oxide. Indium-111 oxine in plasma resulted in a moderate LE and required a longer incubation time, while [111In]oxine sulfate had low LE and inconsistent labeling. High LE for all forms of [111In]chelates were achieved in labeling media free of plasma. However, in vivo platelet survival in rabbits was markedly reduced when platelets were labeled in the absence of plasma.     

Tibial-talar dislocation without fracture: treatment principles and outcome

The incidence of tibial-talar dislocations without fracture is unknown and has been sparsely reported in the literature. The diagnosis of the injury is straightforward with the appropriate examination and roentgenograms. Good to excellent results can be achieved with open or closed dislocations treated by closed reduction and immobilization for 4–6 weeks. Although open dislocations require irrigation, debridement, and possibly delayed closure, controversy exists with regard to acute ligament repair. Because good to excellent results are possible without acute ligament repair, and delayed repair on reconstruction can be accomplished with good outcomes, we recommend treating these injuries without ligament repair.     

Acute coronary syndromes

The diagnosis of myocardial infarctionshould be qualified by size, causation and time from occurrence. Mortalityis reduced by immediate or ‘primary’ percutaneouscoronary intervention or thrombolysis within the first 24 hof onset of ST-segment elevation myocardial infarction. Strategiesto reduce platelet activation (glycoprotein IIb/IIIa receptorantagonists, or clopidogrel) are now recommended in the treatmentof high-risk non-ST-segment myocardial infarction/unstable angina. Elevatedserum troponins may be the result of non-ischaemic myocardialdamage, especially in critical illness.
