- The aims of the study were to investigate self-reported physical, sexual, emotional and economical abuse in Swedish female users of psychiatric services, who the perpetrators were and in which places abuse occurred. An anonymous self-administrated questionnaire was answered in the waiting room of the services. The drop-out rate was 21% and n=1382 women completed the questionnaire. Fifty-three per cent of the women had been abused during childhood, 63% during adulthood and 31% during past year. Seventy-four per cent of those exposed during childhood were also exposed later in life. Women subjected to abuse reported longer contact with psychiatric care. Regardless of life period, the majority reported multiple and frequent abuse. Emotional abuse was most frequent reported in both childhood and adulthood followed by physical and sexual abuse. The reported perpetrators were mainly male persons to whom the woman had an intimate relationship. Mostly the abuse occurred in the women's own home. However, other women, strangers, acquaintances and relatives were also stated as perpetrator and abusive acts also took place in other homes, outdoors or down town. The high prevalence of abuse and its multiplicity point to the necessity for the care and support system to prioritize abuse against women with psychiatric illness.

- The lower inflection point (LIP) of the inspiratory limb of a static pressure-volume (PV) loop is assumed to indicate the pressure at which most lung units are recruited. The LIP is determined by a static manoeuvre with a PV-history that is different from the PV-history of the actual ventilation. In nine surfactant-deficient piglets, information to allow setting PEEP and VT was obtained, both from the PV-curve and also during ongoing ventilation from the dynamic compliance relationship. According to LIP, PEEP was set at 20 (95% confidence interval 17-22) cm H2O. Volume-dependent dynamic compliance suggested a PEEP reduction (to 15 (13-18) cm H2O). Pulmonary gas exchange remained satisfactory and this change resulted in reduced mechanical stress on the respiratory system, indirectly indicated by volume-dependent compliance being consistently great during the entire inspiration.

- BACKGROUND:Short periods of sustained increase in airway pressures (Press(up)) are believed to re-open lung areas that collapsed upon induction of anaesthesia. Recruitment of alveolar surface is usually assessed in terms of changes in the pressure-volume (PV) curve. The purpose of this study was to analyse PV-curves before and after a Press(up) and to ascertain whether such changes are compatible with the concept of recruitment of lung volume.METHODS:During ketamine anaesthesia, 12 healthy piglets were subjected to a Press(up) with end-expiratory pressure (PEEP) of 12 cmH2O and end-inspiratory pressure of 40 cmH2O. Before and after Press(up), PV-curves were obtained from a slow insufflation of 630 ml at zero PEEP (ZEEP).RESULTS:Compliance was non-linear both before and after Press(up) increasing up to 300 ml and sharply decreasing thereafter. After Press(up), the entire compliance curve was shifted to a higher absolute level. Up to 100 ml and a pressure level corresponding to the lower inflection point on the PV-curve (LIP), compliance was higher before Press(up). No effects on blood gases could be observed.CONCLUSION:If the similar shape of the compliance curve corresponds to a similar chain of re-opening and overdistension events, this would imply that all volume gained by Press(up) is lost within 10 min, without explaining the higher absolute compliance following Press(up). We speculate that a) re-opening of rapidly collapsing small airways determines the initial compliance increase; b) the lower compliance after Press(up) until LIP indicates reduced intratidal re-opening of lung regions; and c) changes in bronchomotor tone induced by Press(up) raise the absolute compliance, with a similar scenario of alveolar and small airway recruitment now taking place but at different degrees of airway stiffness.
