RESUMO

BACKGROUND: Cardiovascular disease (CVD) is a common comorbidity in chronic obstructive pulmonary disease (COPD) and reduced lung function is an important risk factor for CVD and CVD-related death. However, the mechanisms behind the increased risk for CVD in COPD patients are not fully understood. METHODS: We examined the association between CVD- and inflammation-related serum biomarkers, and pulmonary function in a geriatric population. 266 biomarkers related to CVD and inflammation were analyzed in blood samples from 611 subjects aged 66-86 years who participated in the Good Aging in Skåne study. Serum levels were assessed by a proximity extension assay. Pulmonary function was measured using the lower limit of normality (LLN) spirometry criteria, i.e., forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) < LLN. Logistic regression models were implemented and multiple comparisons were accounted for. RESULTS: 10.3% of the study participants fulfilled pulmonary function decline criteria according to LLN. Out of the 266 biomarkers, only plasminogen activator, urokinase receptor (PLAUR) was statistically significantly associated with decreased pulmonary function. We could not find a statistically significant association between pulmonary function decline and other biomarkers previously linked to COPD, such as interleukin 6, tumor necrosis factor and surfactant protein D. CONCLUSION: We found that serum levels of PLAUR are associated with pulmonary function decline in older adults. PLAUR is activated following inflammation and promotes matrix metallopeptidase (MMP) activation and extracellular matrix (ECM) degradation. This implies that PLAUR could play a role in the early phase of COPD pathogenesis.

RESUMO

BACKGROUND AND AIMS: The optimal extent of mesenteric resection in colon cancer surgery remains elusive. The aim was to assess the impact on perioperative morbidity and oncological outcome depending on the height of central vessel ligation in sigmoid resection for adenocarcinomas. MATERIAL AND METHODS: All cases of stage I-III sigmoid cancers, operated on with locally radical resections (2007-2009), were identified in the Swedish Colorectal Cancer Registry and categorized according to the position of the vascular ligature, that is, ligation of the inferior mesenteric artery, ligation of the superior rectal artery, or ligation of the sigmoid branches. RESULTS: In total, 999 cases were identified and possible to categorize. Although higher ligation level yielded a higher number of lymph nodes, 3- or 5-year overall survival, 5-year disease-free survival, or recurrence rate did not differ between the groups (p = 0.79, p = 0.41, p = 0.67, p = 0.51). No differences in survival were detected after multivariate analysis adjusted for age, sex, T-stage, N-stage, American Society of Anesthesiologists classification, and adjuvant therapy. CONCLUSION: This large population-based study showed increased lymph node yield but no survival benefit or any decreased recurrence rate by high tie in resection of sigmoid cancer.

RESUMO

BACKGROUND: Coffee drinking has been implicated in mortality and a variety of diseases but potential mechanisms underlying these associations are unclear. Large-scale systems epidemiological approaches may offer novel insights to mechanisms underlying associations of coffee with health. OBJECTIVE: We performed an analysis of known and novel protein markers linked to cardiovascular disease and their association with habitual coffee intake in the Prospective Study of the Vasculature in Uppsala Seniors (PIVUS, n = 816) and followed up top proteins in the Uppsala Longitudinal Study of Adult Men (ULSAM, n = 635) and EpiHealth (n = 2418). METHODS: In PIVUS and ULSAM, coffee intake was measured by 7-day dietary records whilst a computer-based food frequency questionnaire was used in EpiHealth. Levels of up to 80 proteins were assessed in plasma by a proximity extension assay. RESULTS: Four protein-coffee associations adjusted for age, sex, smoking and BMI, met statistical significance in PIVUS (FDR < 5%, P < 2.31 × 10-3 ): leptin (LEP), chitinase-3-like protein 1 (CHI3L), tumour necrosis factor (TNF) receptor 6 and TNF-related apoptosis-inducing ligand. The inverse association between coffee intake and LEP replicated in ULSAM (ß, -0.042 SD per cup of coffee, P = 0.028) and EpiHealth (ß, -0.025 SD per time of coffee, P = 0.004). The negative coffee-CHI3L association replicated in EpiHealth (ß, -0.07, P = 1.15 × 10-7 ), but not in ULSAM (ß, -0.034, P = 0.16). CONCLUSIONS: The current study supports an inverse association between coffee intake and plasma LEP and CHI3L1 levels. The coffee-CHI3L1 association is novel and warrants further investigation given links between CHI3L1 and health conditions that are also potentially influenced by coffee.

RESUMO

OBJECTIVES: Post-stroke cognitive impairment (PSCI) has considerable impact on patients and society. However, long-term studies on PSCI are scarce and may be influenced by assessment methods and selection bias. We aimed to (i) assess the prevalence of long-term PSCI; (ii) compare two common cognitive assessment instruments; and (iii) compare cognitive function of long-term stroke survivors with non-stroke persons. METHODS: Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were administered to 10-year survivors from a population-based cohort of first-ever stroke patients included in the Lund Stroke Register, Sweden, in 2001-2002. PSCI was defined as MMSE<27 and/or MoCA<25 and severe cognitive impairment as MMSE<23. Age- and sex-matched non-stroke control subjects who had performed MMSE (but not MoCA) were recruited from the longitudinal population study "Good Ageing in Skåne." The odds of having cognitive impairment for stroke survivors compared to controls were examined with logistic regression analyses adjusting for education. RESULTS: Of 145 stroke survivors after 10 years, 127 participated. MMSE showed PSCI in 46%, whereas MoCA displayed PSCI in 61%. Among the stroke survivors with MoCA<25, 35% had MMSE≥27 (P<.001). The odds of having severe cognitive impairment defined as MMSE<23 were higher among the stroke survivors compared to 354 controls (education-adjusted; OR=2.5; P=.004). CONCLUSIONS: Post-stroke cognitive impairment was prevalent among 10-year stroke survivors, and the odds of having severe cognitive impairment were higher among the stroke survivors compared to non-stroke persons. The burden of long-term PSCI might have been underestimated previously, and MoCA may be more suitable than MMSE to detect long-term PSCI.

RESUMO

OBJECTIVES: Study formal and informal care of community-living older people in the Swedish National study of Aging and Care (SNAC). DESIGN: Cross-sectional, population based cohort. SETTING: Three areas in Sweden: Municipality of Nordanstig, Stockholm and Skåne County. PARTICIPANTS: 3,338 persons ≥72 years. MEASUREMENTS: Patterns and amounts of informal and formal care by cognition and area of residence. RESULTS: 73% received no care; 14% formal care; and 17% informal care (7% received both). In the whole study population, including those who used no care, individuals in small municipalities received 9.6 hours of informal care/month; in mid-size municipalities, 6.6; and in urban areas, 5.6. Users of informal care received 33.1 hours of informal care/month in small municipalities, 54.6 in mid-size municipalities and 36.1 in urban areas. Individuals with cognitive impairment received 14.1 hours of informal care/month, 2.7 times more than people with no/slight impairment. In the whole study population, individuals in small municipalities received an average of 3.2 hours of formal care/month; in mid-size municipalities 1.4; and in urban areas, 2.6. Corresponding figures for formal care users were 29.4 hours in small municipalities, 13.6 in mid-size municipalities and 16.7 in urban areas. Formal care users received 7.1 hours, and informal care users, 5.9 hours for each hour/month received by people in the study population as a whole. CONCLUSIONS: More informal than formal care was provided. Informal care is more frequent in small municipalities than urban areas and for those with than without cognitive impairment. The relationship between data on the whole population and the data on users or care indicates that population-based data are needed to avoid overestimates of care.

RESUMO

AIM: The optimal extent of mesenteric resection in colon cancer surgery is not known. We have previously shown an increased mortality associated with wider mesenteric resection in right hemicolectomy. This study compares the short- and long-term outcome in three variations of right hemicolectomy based on the position of the vascular ligature in the mesentery. METHOD: In all, 2084 cases of cancer in the caecum or ascending colon were identified in the Swedish Colorectal Cancer Registry and categorized according to the position of the vascular ligature: central ligation of ileocolic vessels (ICVs) ± right colic vessels (n = 390), central ligation of ICVs + right branch of middle colic vessels (MCVs) (n = 1360) and central ligation of ICVs + central ligation of MCVs (n = 334). RESULTS: Neither 3-year overall survival, 3-year disease-free survival nor local recurrence rate differed between the groups (P = 0.604; P = 0.247; P = 0.237). There was still no difference after multivariate analysis adjusted for age, sex, American Society of Anesthesiologists classification, TNM stage and adjuvant therapy. An increased peri-operative mortality, however, was observed in extended mesenteric resections, increasing from 0.8% in non-extended to 3.6% in more extended resection, P = 0.025. CONCLUSION: The study showed no survival benefit by more extended mesenteric resection, indicating that there is no need to extend the mesenteric resection to involve the MCVs in cancer of the caecum or ascending colon. On the contrary, increased peri-operative mortality by more extensive mesenteric resection was noted suggesting that a more conservative approach may be favourable.

RESUMO

Previous observational studies on the association between brachial blood pressure (BP) and cognition have reported conflicting results. Central BP has been hypothesized to be more strongly related to cognition than brachial BP. The aim of this study was to assess the association between brachial as well as central BP and cognitive function, both cross-sectionally and with brachial BP measured 17 years before cognitive testing. The study population comprised 2548 individuals aged 61-85 years at follow-up (61.4% women). The cognitive tests administered were A Quick Test of cognitive speed and the Mini Mental State Examination. In fully adjusted linear regressions, small but significant cross-sectional associations were found between higher BP (systolic, diastolic and pulse pressure) and worse results on both of the cognitive tests (P-values <0.05). No significant prospective associations were found. Central BP did not show a stronger association than brachial BP did. After stratification, significant results were mainly found in the group taking BP-lowering drugs at follow-up. In summary, these findings add to existing evidence on the relationship between BP and cognition, but they do not support a superior role of central compared with brachial BP in the elderly.

RESUMO

BACKGROUND/OBJECTIVES: Anthropometric measurement is a noninvasive and cost-efficient method for nutritional assessment. The study aims to present age- and gender-specific anthropometric reference data for Swedish elderly in relation to common medical conditions, and also formulate prediction equations for such anthropometric measurements. SUBJECTS/METHODS: A cross-sectional study among random heterogeneous sample of 3360 subjects, aged 60-99 years, from a population study 'Good Aging in Scania. Means (±s.d.) and percentiles for height, weight, waist-, hip-, arm-, calf circumferences, triceps- (TST) and subscapular skinfold thickness (SST), body mass index (BMI), waist-hip ratio (WHR) and arm muscle circumference (AMC) were presented. The values were estimated based on the prevalence of myocardial infarction (MI), cardiac failure (CHF), stroke, cognitive impairment, dementia and dependence in daily living activities (ADL). Linear regression analysis was used to formulate the prediction equations. RESULTS: Mean BMI was 27.5±5.8 kg/m(2) (men) and 27.2±8.1 kg/m(2) (women). WHR was higher among men (Men: 0.98±0.3, women: 0.87±0.2), except at age 85+ (women: 0.91±0.6). TST was 6.7±0.4 mm higher among women. Men with MI had BMI: 28.6±4.8 kg/m(2) and SST: 21±9.2 mm, whereas subjects with dementia had lower weight (by 9.5±2.9 kg) compared with the non-demented. ADL-dependent women had BMI= 29.0±3.9 kg/m(2), TST=19.2±1.3 mm. CONCLUSION: New normative data on gender- and age-specific anthropometrics on the general elderly population are presented. Cardiovascular diseases are associated with subcutaneous and central adiposity opposed to fat loss with dementia. ADL dependence indicates inadequate physical activity. The prediction models could be used as possible indicators monitoring physical activity and adiposity among the general elderly population hence potential health indicators in health promotion.

RESUMO

BACKGROUND/OBJECTIVES: The degree of misclassification of obesity and undernutrition among elders owing to inaccurate height measurements is investigated using height predicted by knee height (KH) and demispan equations. SUBJECTS/METHODS: Cross-sectional investigation was done among a random heterogeneous sample from five municipalities in Southern Sweden from a general population study 'Good Aging in Skåne' (GÅS). The sample comprised two groups: group 1 (KH) including 2839 GÅS baseline participants aged 60-93 years with a valid KH measurement and group 2 (demispan) including 2871 GÅS follow-up examination participants (1573 baseline; 1298 new), aged 60-99 years, with a valid demispan measurement. Participation rate was 80%. Height, weight, KH and demispan were measured. KH and demispan equations were formulated using linear regression analysis among participants aged 60-64 years as reference. Body mass index (BMI) was calculated in kg/m(2). RESULTS: Undernutrition prevalences in men and women were 3.9 and 8.6% by KH, compared with 2.4 and 5.4% by standard BMI, and more pronounced for all women aged 85+ years (21% vs 11.3%). The corresponding value in women aged 85+ years by demispan was 16.5% vs 10% by standard BMI. Obesity prevalences in men and women were 17.5 and 14.6% by KH, compared with 19.0 and 20.03% by standard BMI. Values among women aged 85+ years were 3.7% vs 10.4% by KH and 6.5% vs 12.7% by demispan compared with the standard. CONCLUSIONS: There is an age-related misclassification of undernutrition and obesity attributed to inaccurate height estimation among the elderly. This could affect the management of patients at true risk. We therefore propose using KH- and demispan-based formulae to address this issue.

RESUMO

BACKGROUND AND AIMS: Nodal involvement is the most important prognostic factor in colon cancer. Although theoretically appealing, it is not known if wider mesenteric excision improves the oncological result. The aim of this retrospective study was to investigate whether wider mesenteric excision yields a superior oncological result. MATERIAL AND METHODS: Depending on the resection length, 333 cases of locally radical right-sided hemicolectomies due to adenocarcinoma were compared for perioperative morbidity and mortality, disease-free survival, and long-term survival. RESULTS: Postoperative mortality was significantly higher in the quartile with the longest resections, p = 0.003. In a multivariate analysis adjusted for age, stage, emergency operation, adjuvant chemotherapy, and year of operation, a negative relationship between resection length and 5-year overall survival was noted, p = 0.01. No differences in the causes of death or in the incidence of local or distant recurrences were noted between groups. CONCLUSIONS: Wider excision in right-sided hemicolectomies was not associated with any oncological benefit but an increased postoperative mortality and a decreased 5-year overall survival. These findings may suggest consideration to perform wide mesenteric resections routinely. Further research is warranted to define which patients benefit from wider resections.

RESUMO

BACKGROUND/AIMS: Motor impairment is an important aspect of cognitive decline in older adults. It has been suggested that complex motor control is affected earlier than gross motor control. The aims were to investigate if complex hand motor function was more affected than gross motor function in cognitively impaired older subjects, and to present reference values. METHODS: Alternating forearm movements and grip strength were studied in 301 cases, 419 intermediates and 1,207 controls, aged 60-93 years, controlling for demographic, health-related and functional factors and comorbidity. Global cognitive function was assessed by the Mini-Mental State Examination, and episodic memory by 3-word delayed recall. Grip strength was assessed by the Grippit(R). The frequency of alternating movements during 10 s was registered electronically. RESULTS: Alternating movements but not grip strength was associated with cognitive impairment (right: p = 0.006; left: p = 0.022). The mean alternating movements for the 70-year-old male cases compared to the controls were 2.3 versus 2.5 Hz for the right, and 2.2 versus 2.4 Hz for the left arm (p < 0.05), and for the 60-year-old women 2.0 versus 2.3 Hz for the right arm (p < 0.05). CONCLUSION: Complex but not gross hand motor function is associated with early cognitive impairment.

RESUMO

Acute thromboembolic occlusion in the superior mesenteric artery (SMA) is a condition with high mortality and morbidity. Multi-detector computerised tomography with intravenous contrast enhancement (MDCTiv) may improve diagnostic accuracy and survival. Patients with acute SMA occlusion were identified between 2004 and 2008 at Malmö University Hospital, Sweden. Medical records were analysed. Each MDCTiv was re-evaluated. A total of 67 patients were identified with SMA occlusion, of which 36 were examined with MDCTiv and ten with plain MDCT without intravenous contrast. In all, 24 (67%) of the 36 patients were correctly diagnosed by MDCTiv at first evaluation. Clinical suspicion of intestinal ischemia followed by a distinct inquiry for intestinal ischemia was associated with trend for a higher rate of correct radiological diagnosis, 18 of 23 (78%), at first evaluation (0.06) but without affecting in-hospital survival (p = 0.27). At re-evaluation, SMA occlusion was found in all cases with MDCTiv, whereas intestinal findings were present in half. In-hospital mortality rate was 42% for patients who underwent MDCTiv, which was significantly lower compared to 90% for the ten patients examined with plain MDCT (p = 0.007) and 71% for patients not examined with MDCTiv or plain MDCT (p = 0.031). Patients that underwent plain MDCT had higher levels of creatinine compared to those examined with MDCTiv (p = 0.005). Patients who underwent intestinal revascularisation, endovascular or open, had higher survival rate (p = 0.001). Examination with MDCTiv in patients with acute SMA occlusion was associated with survival benefit. Hence, MDCTiv seems to be the method of choice in the workup phase. Radiologists should routinely describe the mesenteric vessels in patients with acute abdomen even when the diagnosis is not asked for. Patients with high creatinine levels are at risk to be examined without intravenous contrast, and survival in these patients is poor.

RESUMO

Environmental contaminants such as cadmium and persistent organochlorine pollutants have been proposed as risk factors of osteoporosis, and women may be at an increased risk. To assess associations between exposure to cadmium and two different POPs (2,2',4,4',5,5'-hexachlorobiphenyl CB-153, 1,1-dichloro-2,2-bis(p-chlorophenyl)-ethylene p,p'-DDE), on one hand, and bone effects, on the other, in a population-based study among postmenopausal (60-70 years) Swedish women with biobanked blood samples. The study included 908 women and was designed to have a large contrast of bone mineral densities, measured with a single photon absorptiometry technique in the non-dominant forearm. Biochemical markers related to bone metabolism were analyzed in serum. Exposure assessment was based on cadmium concentrations in erythrocytes and serum concentrations of CB-153 and p,p'-DDE. Cadmium was negatively associated with bone mineral density and parathyroid hormone, positively with the marker of bone resorption. However, this association disappeared after adjustment for smoking. The major DDT metabolite (p,p'-DDE) was positively associated with bone mineral density, an association which remained after adjustment for confounders, but the effect was weak. There was no evidence that the estrogenic congener (CB-153) was associated with any of the bone markers. In conclusion, no convincing associations were observed between cadmium and POPs, on one hand, and bone metabolism markers and BMD, on the other.

RESUMO

Cerebrovascular disease may be linked with vascular autoregulation in aging. The aim of this study was to examine relation between nocturnal blood pressure (BP) fall and cerebral blood flow (CBF) changes in elderly men. The prospective 'Men born in 1914' cohort study has been in progress since 1968 and included 809 subjects. After 14 years from the last follow up, 97 subjects reached the age of 82 and underwent CBF measurement and 24 h ambulatory blood pressure monitoring. Diastolic BP at night decreased in 84 subjects with median 12.7% and increased in 13 subjects with median 3.7%. Relative diastolic BP fall at night was negatively associated to CBF in temporal and infero-parietal areas. Higher proportion of subjects with increasing systolic BP during the 14-year period was observed in the subgroup with extreme nocturnal diastolic BP dip, irrespectively of BP values or prevalence of hypertension. Extreme nocturnal diastolic BP fall in a cohort of elderly men is correlated with focal changes in CBF. Further studies could explain if increasing BP in the elderly is a cause or result of pathological autoregulation, and if antihypertensive treatment increases nocturnal BP dip.

RESUMO

PURPOSE: To evaluate the use and findings of abdominal plain film in acute ischemic bowel disease (AIBD) in different age subsets, and to correlate the clinical findings. MATERIAL AND METHODS: Eighty-nine radiographically examined patients with AIBD at Malmö University Hospital, Sweden between 1987 and 1996. RESULTS: In 89%, the plain film displayed pathologic signs. Bowel dilatation was more common in the elderly. Of 68 patients aged > or = 71 years, 19 (28%) had colon gas/fluid levels with/without colon dilatation, and of 19 patients > 84 years 16 (84%) had small-bowel dilatation. Of 20 patients aged < 71 years, 1 (5%) had colon gas/fluid levels with/without colon dilatation, and 11 (55%) small-bowel dilatation (P < 0.05; P < 0.05). Gasless abdomen was more common in the younger age group, noted in 5 of 20 (25%) patients aged < 71 years, compared to 2 of 68 (3%) patients aged > or = 71 years (P = 0.001). Of the patients with diarrhea, 13 of 33 (40%) had colon gas/fluid levels with/without colon dilatation compared to 2 of 29 (7%) without (P = 0.003). In the elderly (> or = 71 years), 48 of 53 (91%) patients with bowel dilatation on plain film died, compared to 11 out of 16 (69%) without this finding (P < 0.05). CONCLUSION: Abdominal plain film findings differed with age. Bowel dilatation was more frequent in the elderly with AIBD, whereas gasless abdomen was more common in younger patients. The radiographic findings were associated with clinical symptoms and mortality.

RESUMO

UNLABELLED: Movement time is increased in patients with Alzheimer's disease. OBJECTIVES: To study differences in movement time and ability to increase speed in older women with dementia. METHODS: Four tests were performed at self-selected and maximal speed: walking 2 x 15 m, walking between parallel lines, 'get up and go' (GUG) and rising from lying supine. Twenty-two patients and 22 controls (mean ages 81 and 86 years, respectively) were included in the study. RESULTS: In the groups over 80 years, walking and GUG at both speeds and rising from lying supine from the left at self-selected speed were significantly slower among patients (20-30%). Both patients and controls were able to increase movement speed when changing from self-selected to maximal speed (13-27%). Patients with Alzheimer's disease had lower self-selected walking speed compared with patients with other types of dementia (p = 0.048). CONCLUSION: Testing physical performance in two different speeds was feasible in patients with dementia. Patients had slower gait speed and were slower in the functional tests, such as GUG, but the capacity to increase speed seemed intact.

RESUMO

OBJECTIVE: To investigate differences in different aspects of social participation and social capital among baseline daily smokers that had remained daily smokers, become intermittent smokers, or stopped smoking at one year follow up. DESIGN/SETTING/PARTICIPANTS/MEASUREMENTS: 12,507 individuals, aged 45-69 years, interviewed at baseline between 1992 and 1994 and at a one year follow up were investigated in this longitudinal study. The three groups of baseline daily smokers were compared to the reference population (baseline intermittent smokers and non-smokers) according to different aspects of social participation and social capital. A multivariate logistic regression model was used to assess differences in different aspects of social participation and social capital. RESULTS: The baseline daily smokers that remained daily smokers at the one year follow up had significantly increased odds ratios of non-participation in study circles in other places than at work, meeting of organisations other than unions, theatre/cinema, arts exhibition, church, sports events, large gatherings of relatives, and private parties compared to the reference population. The baseline daily smokers that had become intermittent smokers at the one year follow up had significantly increased odds ratios of non-participation in church services. The baseline daily smokers that had stopped smoking had increased odds ratios of non-participation in having attended a meeting of organisations other than labour unions during the past year, having been to a theatre or cinema, and of having visited an arts exhibition during the past year. All three categories of baseline daily smokers had significantly decreased odds ratios of non-participation in night club/entertainment. CONCLUSIONS: The baseline daily smokers that had remained daily smokers at the one year follow up had particularly high rates of non-participation compared to the reference population in both activities specifically related to social capital, such as other study circles, meetings of organisations other than labour unions, and church attendance and cultural activities such as theatre/cinema and arts exhibition, although significantly lower participation in cultural activities and meetings of other organisations was also observed among daily smokers that had stopped smoking. All three baseline daily smoker groups had higher rates of having visited a night club during the past year.

RESUMO

One hundred and sixty-eight men who were participants in the study "Men born in 1914" had their blood pressure and cognitive function examined when they were 68 years old. They were then re-examined at the age of 81. Decline on five standardized cognitive tests at the age of 81 years was studied in relation to four levels of baseline blood pressure at the age of 68. Results from multivariate analyses suggested that blood pressure, when studied in conjunction with other factors related to cognitive function, contribute to a rather modest extent and not unambiguously to the variability in cognitive decline. When decline on each separate test had been combined into a composite measure, where equal weight had been given to memory, crystallized and fluid abilities, it was shown that hypertension stage 2 (SBP 160-179 mmHg or DBP 100-109 mmHg) was associated with greater levels of overall decline. Hypertension stage 3 (SBP > or =180 mmHg or DBP > or =110 mmHg), on the other hand, was associated with lower levels of overall decline. Depressive symptoms at follow-up had a negative effect on cognitive levels and were discussed as potential confounders of hypertension-related cerebral lesions.
