Long‐term effects of using oral care aides at a nursing home for elderly dependent residents—a pilot study

The oral health status of elderly dependent residents is reported to be poor, as well as difficult to describe. Analysis of oral microbial flora has been suggested as a suitable measurement method. Oral care aides have been shown to have a positive influence on oral health care in nursing. The outcome of an intervention with oral care aides was followed during a two‐year period by recording: (a) the proportion of opportunistic microorganisms and bacteria associated with caries (b) whether oral hygiene assistance were given to the residents or not, and (c) individual experiences concerning oral health care among the staff involved. The oral flora and the amount of oral hygiene assistance improved throughout the entire study period, but staff interviews revealed that it took two years for good cooperation and prophylactic routines to be established. An unexpected finding was the positive correlation (p = .0005) between a high proportion of the opportunistic microorganisms and death within one year.     

Superior fixation and less periprosthetic stress-shielding of tibial components with a finned stem versus an I-beam block stem: a randomized RSA and DXA study with minimum 5 years’ follow-up

Background and purpose — The stem on the tibial component of total knee arthroplasty provides mechanical resistance to lift-off, shear forces, and torque. We compared tibial components with finned stems (FS) and I-beam block stems (IS) to assess differences in implant migration.

Patients and methods — In a patient-blinded RCT, 54 patients/knees (15 men) with knee osteoarthritis at a mean age of 77 years (70–90) were randomly allocated to receive tibial components with either a FS (n = 27) or an IS (n = 27). Through 5 to 7 years’ follow-up, implant migration was measured with RSA, periprosthetic bone mineral density (BMD) was measured with DXA, and surgeons reported American Knee Society Score (AKSS).

Results — At minimum 5 years’ follow-up, maximum total point motion (MTPM) was higher (p = 0.04) for IS (1.48?mm, 95% CI 0.81–2.16) than for FS (0.85?mm, CI 0.38–1.32) tibial components. Likewise, total rotation (TR) was higher (p = 0.03) for IS (1.51?, CI 0.78–2.24) than for FS (0.81?, CI 0.36–1.27). Tibial components with IS externally rotated 0.50° (CI –0.06 to 1.06) while FS internally rotated 0.09° (CI –0.20 to 0.38) (p = 0.03). Periprosthetic bone stress-shielding was higher (p < 0.01) up to 2 years’ follow-up for IS compared with FS in the regions medial to the stem (–13% vs. –2%) and posterior to the stem (–13% vs. –2%). Below the stem bone loss was also higher (p = 0.01) for IS compared with FS (–6% vs. +1%) up to 1-year follow-up. Knee score improved similarly in both groups up to 5 years’ follow-up.

Interpretation — Periprosthetic bone stress-shielding medial and posterior to the stem until 2 years, and tibial component migration at 5 years, was less for a finned compared with an I-shaped block stem design.

Making Meals in Small Seasonal Restaurants

Since restaurateurs can benefit by analyzing the production of meals, particularly with the dominant framework for meal experiences, the five aspects meal model (FAMM), this study examined FAMM’s relevance as an analytical tool for understanding meal production via field observations and interviews in eight small restaurants in a rural destination in Sweden. Results showed that FAMM’s aspect of the management control system and the factor of time are critical to the entire meal production process in restaurants. This article closes with a discussion of FAMM’s usefulness as a qualitative checklist for restaurateurs.     

War Experiences and General Health Among People in Bosnia‐Herzegovina and Kosovo

War experiences may have an extensive impact on the health status of the exposed populations. This population‐based study aimed to examine the relationship between war experiences and self‐reported general health in representative sample surveys from Bosnia‐Herzegovina (n = 3,313) and Kosovo (n = 1,000). Data were collected with face‐to‐face interviews fielded in the winter of 2003–2004. Logistic regression analysis was used to compute unadjusted and adjusted odds ratios (ORs). The adjusted effects of the extensiveness of war experiences on poor health were positive in both countries, but they were statistically significant only for Bosnia‐Herzegovina: OR = 1.04, 95% CI [1.00, 1.08] for Bosnia‐Herzegovina and OR = 1.03, 95% CI [0.98, 1.09] for Kosovo. The strongest observed effect was found for Kosovo only: The extensiveness of war experiences was relatively strongly related to longstanding health problems, OR = 1.09, 95% CI [1.03, 1.15]. We found that war experiences may contribute to increased poorer health in the exposed populations; however, the effects 4–9 years after the war ended were modest. Hence, war experiences seemed to be more strongly related to war‐related distress and posttraumatic stress disorder than to self‐reported general health.     

The prevalence of retinopathy in subjects with and without type 2 diabetes mellitus

Purpose:  To evaluate the prevalence of and risk factors for, retinopathy in a geographically defined population with type 2 diabetes mellitus compared with a control group of subjects without diabetes, matched by age, sex and residence in order to find the retinopathy attributable to type 2 diabetes. Methods:  The study populations are, on one hand, a prevalence cohort of subjects with type 2 diabetes resident in the community of Laxå, Sweden, and on the other a control group, matched by age, gender and residence with those with a diagnosis of type 2 diabetes mellitus. Retinopathy was graded from fundus photographs using a modification of the Early Treatment Retinopathy Study (ETDRS) adaptation of the modified Airlie House classification of diabetic retinopathy (DR). Results:  Any retinopathy was found in 34.6% in the type 2 diabetes cohort and in 8.8% in the control group without diabetes. Among the diabetic patients, any retinopathy was significantly associated with duration of diabetes (p = 0.0001), HbA1c (p = 0.0056), systolic blood pressure (p = 0.0091) and lower serum cholesterol (p = 0.0197) in multivariate logistic regression analyses. Having retinopathy in the control group was associated only with systolic blood pressure (p = 0.0014) in logistic regression analysis. Conclusions:  The prevalence of retinopathy among patients with type 2 diabetes in Laxå, Sweden, was similar or somewhat lower compared with other studies in the Nordic countries. The prevalence of retinopathy in a control group without diabetes equalled numbers from population studies worldwide. Our study indicates that the retinopathy that can be attributed to hyperglycaemia in the diabetic state is less common than is usually accounted for. A considerable fraction of retinopathy in subjects with diabetes may instead be due to other factors such as hypertension and should thus be treated correspondingly.
