- BACKGROUND: Hyaluronan may be used as a marker for malignant mesothelioma, thus indicating its mesodermal origin. METHODS: The sensitivity as a diagnostic test of three different methods for hyaluronan analyses of pleural fluid was examined in patients with biopsy-verified malignant pleural mesothelioma. RESULTS: A quantitative high-performance liquid-chromatography (HPLC) method was performed on fluids from 43 patients. Using a cutoff level of 100 mg/l, higher levels were noted in 30 (70%) patients, with a median value of 220 mg/l (mean, 560 mg/l; range, 20-6600 mg/l). An identical median value (220 mg/l) was obtained with a radioassay method when simultaneously performed on paired samples from 21 patients (correlation coefficient, 0.91). A qualitative precipitation test using 0.5% cetylpyridinium chloride combined with a quantitative viscosimetric method was significantly less sensitive (P < 0.01). CONCLUSION: Hyaluronan analyses is beneficial in distinguishing malignant mesothelioma if methods such as the evaluated HPLC or radioassay with a sensitivity of 70% toward mesothelioma are used and other known causes of elevated content are considered.

- BackgroundOut‐of‐hospital cardiac arrest survivors suffer from psychological distress and cognitive impairments. They experience existential insecurity and vulnerability and are striving to return to a life in which well‐being and the meaning of life have partly changed. However, research highlighting the experiences of in‐hospital cardiac arrest survivors is lacking. This means that evidence for postresuscitation care has largely been extrapolated from studies on out‐of‐hospital cardiac arrest survivors, without considering potential group differences. Studies investigating survivors’ experiences of an in‐hospital cardiac arrest are therefore needed.AimTo illuminate meanings of people's lived experiences of surviving an in‐hospital cardiac arrest.DesignAn explorative, phenomenological hermeneutic method to illuminate meanings of lived experiences.MethodParticipants were identified through the Swedish national register of cardiopulmonary resuscitation and recruited from two hospitals. A purposive sample of eight participants, 53–99 years old, who survived an in‐hospital cardiac arrest 1–3 years earlier, was interviewed.FindingsThe survivors were striving to live in everyday life and striving for security. The struggle to reach a new identity meant an existence between restlessness and a peace of mind, searching for emotional well‐being and bodily abilities. The search for existential wholeness meant a quest for understanding and explanation of the fragmented cardiac arrest event and its existential consequences. The transition from hospital to home meant a transition from care and protection to uncertainty and vulnerability with feelings of abandonment, which called for a search for security and belonging, away from isolation and loneliness.ConclusionSurviving an in‐hospital cardiac arrest can be further understood by means of the concept of hospital‐to‐home transition. Following hospital discharge, patients felt vulnerable and abandoned when pending between denial and acceptance of the ‘new’ life. Hence, the healthcare system should play a significant role when it comes to facilitate cardiac arrest survivors’ security during hospital‐to‐home transition.

- The plasma protein transthyretin (TTR) has the potential to form amyloid under certain conditions. More than 50 different point mutations have been associated with amyloid formation that occurs only in adults. It is not known what structural changes are introduced into the structure of this otherwise stable molecule that results in its aggregation into insoluble amyloid fibrils. On the basis of calculations of the frequency of known mutations over the polypeptide, we have constructed two mutants in the D-strand of the polypeptide. These molecules, containing either a deletion or a substitution at amino acid positions 53−55, were unstable and spontaneously formed aggregates upon storage in TBS (pH 7.6). The precipitates were shown to be amyloid by staining with thioflavin T and Congo Red. Their ultrastructure was very similar to that of amyloid fibrils deposited in the vitreous body of patients with familial amyloidotic polyneuropathy type 1 with an amino acid replacement in position 30 (TTRmet30). Like amyloid isolated from the vitreous body of the eye, the amyloid precipitates generated from the TTR mutants exposed a trypsin cleavage site between amino acid residues 48 and 49, while plasma TTRmet30 isolated from amyloidosis patients as well as wild-type TTR only showed minor trypsin sensitivity. Our data indicate that the mutants we have constructed are similar to amyloid precursors or may share structural properties with intermediates on a pathway leading to amyloid deposits of plasma TTR.

Effect of lung volume reduction surgery for emphysema on diaphragm function

- Preoperative prediction of a successful outcome following lung volume reduction surgery (LVRS) for emphysema is imperfect. One mechanism could be improvement in respiratory muscle function yet controversy exists regarding the magnitude and mechanism of such an improvement. Therefore, we measured diaphragm strength in 18 patients before and after LVRS. Mean (S.D.) FRC fell from 6.53 to 5.40l (p=0.0001). Mean sniff transdiaphragmatic pressure increased from 76 to 87cmH(2)O (14%, p<0.03) and mean twitch transdiaphragmatic pressure (Tw Pdi) increased by 2.5cmH(2)O at 3 months (12%, p=0.03). There was a highly significant increase in twitch esophageal pressure (Tw Pes) (60%, p<0.0001), which was maintained at 12 months (46% increase, p=0.0004). No change was observed in quadriceps twitch tension in nine subjects in whom it was measured. After LVRS the ratio Tw Pes:Tw Pdi increased from 0.24 to 0.37 at 3 months (p=0.0003) and 0.36 at 12 months (p=008). Low values of Sn Pdi, Sn Pes, Tw Pes and a high RV/TLC ratio were the preoperative variables most predictive of improvement in shuttle walking distance. We conclude that LVRS improves diaphragm function primarily by alteration of lung volume. Patients with poor diaphragm function and high RV/TLC ratio preoperatively are most likely to benefit from the procedure.

- AimTo explore factors associated with health-related quality of life (HRQoL) among cardiac arrest (CA) survivors treated with an implantable cardioverter-defibrillator (ICD) in relation to gender, and to compare their HRQoL with a general population.MethodsThis cross-sectional study included 990 adults treated with an ICD after suffering CA. All participants received a questionnaire including demographics, comorbidities and instruments to measure HRQoL (EQ-5D-3L and HADS), ICD-related concerns (ICDC), perceived control (CAS), and type D personality (DS-14). HRQoL (EQ-5D-3L) was compared to a general Swedish population, matched for age and gender. Linear regression analyses were used to explore factors associated with HRQoL.ResultsThe CA survivors reported better HRQoL in EQ index and less pain/discomfort compared to the general population (p < 0.001). In contrast, they reported more problems in mobility and usual activities (p < 0.01). Problems with anxiety and depression were reported by 15.5% and 7.4% respectively. The following factors were independently associated with all aspects of worse HRQoL: being unemployed, suffering more comorbidity, perceiving less control, and having a type D personality. Further, being female and suffering ICD-related concerns were independently associated with worse HRQoL in three of the four final regression models.ConclusionsThis extensive population-based study showed that most CA survivors living with an ICD rate their HRQoL as acceptable. In addition, their HRQoL is similar to a general population. Women reported worse HRQoL compared to men. Several factors associated with HRQoL were identified, and might be used when screening patients for health problems and when developing health promoting interventions.
