Influence of gender on post-tetanic potentiation in human dorsiflexors.

Twitch contractions of the ankle dorsiflexors were evoked before and after 7 s of tetanic stimulation at 100 Hz in young women and men. Torque decreased more in men (18%) than in women (12%) during the tetanus. There was no gender difference in twitch peak torque potentiation over the 5-min post-tetanus. Potentiation was 42% (women) and 45% (men) at 5 s post-tetanus, and still present at 5 min (women 24%, men 25%). The immediate (5 s) shortening of twitch rise time was similar in women (14%) and men (13%), but during the 5-min men's rise time came to exceed whereas women's only approached pretetanus values (e.g., +9% vs. -1% at 5 min). The immediate decrease in half-relaxation time was also similar in women (24%) and men (22%); however, women's but not men's values remained less than pretetanus values for most of the 5-min period. Twitch rate of torque development increased similarly (75%) in women and men at 5 s, with no gender difference over 5 min. In contrast, rate of torque relaxation increased significantly only in men. Rate of torque development normalized to peak torque was similar in women and men pretetanus and increased similarly 5 s post-tetanus, but women had greater values through most of the 5-min post-tetanus. Normalized rate of torque relaxation was similar in women and men and not affected by tetanus. In the dorsiflexor muscles, young women and men show a similar amount and pattern of twitch force potentiation, but there are gender differences in time-related twitch contractile properties in the first 5 min after tetanus.

A survey of the qualifications of ophthalmology nurses.

A study was conducted to ascertain the numbers of nurses working in ophthalmology with appropriate qualifications. A questionnaire was sent to 168 ophthalmic nurse managers in the UK which revealed that a much greater proportion of nurses employed at grades I, H, G and F hold an ophthalmic qualification compared with those employed at grades E, D and C. Those nurses working at higher grades were far fewer in number, however. The results also indicated that the smaller the unit is, the less likely it is to employ nurses holding the specialist qualification. More funding and access to courses is recommended.

Predictors of absenteeism among hospital staff nurses.

An organizational dynamics paradigm is examined for effectiveness in predicting absenteeism among staff RNs in four hospitals. Different predictor variables were important within each hospital. Discussion is focused on the manager role and organizational policies related to criteria for excessive absence, incentives for attendance, and deterrents to absence.
