Pholeter anterouterus Fischthal & Nasir, 1974 (Digenea: Opisthorchiidae) redescribed, together with remarks on the genera Pholeter Odhner, 1914 and Phocitrema Goto & Ozaki, 1930 and their relationship to the centrocestine heterophyids.

Photoleter anterouterus Fischthal & Nasir, 1974, from Pelecanus occidentalis Linnaeus and Pelecanus erythrorhynchos Gmelin from Florida, USA and the ventro-genital complexes of Photeleter gastrophilus (Kossack, 1910) from Delphinus delphis Linnaeus from Queensland, Australia and of Phocitrema fusiforme Goto & Ozaki, 1930 from Alopex lagopus (Linnaeus) and Phoca vitulina Linnaeus from Alaska are redescribed. The genus Photoleter Odhner, 1914 is emended and compared with Phocitrema Goto & Ozaki, 1930 and both genera are compared with members of, and as a result transferred from the family Opisthorchiidae Looss, 1899 to, the subfamily Centrocestinae Looss, 1899, family Heterophyidae Odhner, 1914.

Prevalence of farmer's lung in Scotland: a pilot survey.

In a survey of the farming population of Orkney, Ayrshire, and East Lothian the prevalence of farmer's lung was estimated at 86 per 1,000 in both Orkney and Ayrshire and 23 per 1,000 in East Lothian. If cases with a negative farmer's lung hay (F.L.H.) precipitin test are excluded these figures are reduced to 43, 36, and nil respectively, but those for Orkney and Ayrshire are still about 20 times higher than any figure previously reported for the prevalence of farmer's lung in Britain.Regional variations in prevalence are probably related both to climatic conditions and to differences in agricultural methods, the latter often being dictated by economic circumstances. Nevertheless the prevalence of farmer's lung could be reduced considerably by the energetic application of preventive measures, backed by financial incentives. The most important of these are efficient drying of hay and cereals before storage, more extensive use of silage, better ventilation of farm buildings, and the introduction of mechanical feeding systems. Individual farmworkers could be taught how to recognize the early symptoms of the disease and encouraged to wear respirators when handling mouldy fodder.

Risk factors for hospital-acquired urinary tract infection in a large English teaching hospital: a case-control study.

About 10% of patients in hospital develop a hospital-acquired infection (HAI); the most commonly affected site is the urinary tract. Many studies have examined risk factors for HAI but few have adjusted for confounding and interaction. We performed a prospective case-control study on six acute wards of a busy English teaching hospital to assess risk factors for hospital-acquired urinary tract infection (HAUTI). Over a 2-year period, 136 cases were identified (2.8% of all patient episodes) along with 408 controls. Multiple logistic regression revealed that female sex, increased length of stay, elective admission, surgical operation, and transurethral and repeated intermittent catheterization were all significant independent risk factors for HAUTI. However, specialty of admission was also a significant risk factor when added to the model and, under these conditions, only length of stay and catheterization also remained significant. We detected significant interactions suggesting that the risk of HAUTI is maximal among women undergoing elective surgery, especially those who are catheterized; however, the overall risk of HAUTI among patients admitted electively was greater than for patients admitted as emergencies.

Evaluation of a Wellness-Based Mindfulness Stress Reduction intervention: a controlled trial.

PURPOSE: To determine if participation in a Wellness-Based Mindfulness Stress Reduction intervention decreases the effect of daily hassles, psychological distress, and medical symptoms. DESIGN: A randomized controlled trial of a stress reduction intervention with a 3-month follow-up. SETTING: A university setting in West Virginia. SUBJECTS: A total of 103 adults, with 59 in the intervention group and 44 in the control group. Eight-five percent of subjects completed the intervention. Fifty-nine percent and 61% of the intervention and control subjects completed the study, respectively. INTERVENTION: The intervention consisted of an 8-week group stress reduction program in which subjects learned, practiced, and applied "mindfulness meditation" to daily life situations. The control group received educational materials and were encouraged to use community resources for stress management. MEASURES: The Daily Stress Inventory assessed the effect of daily hassles, the Revised Hopkins Symptom Checklist measured psychological distress, the Medical Symptom Checklist measured number of medical symptoms, and a Follow-up Questionnaire measured program adherence. RESULTS: Intervention subjects reported significant decreases from baseline in effect of daily hassles (24%), psychological distress, (44%), and medical symptoms (46%) that were maintained at the 3-month follow-up compared to control subjects (repeated measures analysis of variance [ANOVA]; p < .05). CONCLUSIONS: Self-selected community residents can improve their mental and physical health by participating in a stress reduction intervention offered by a university wellness program.
