One-bite-sized 3D printed finger foods, oriented to malnutrition, sarcopenia and frailty prevention in the older people.

BACKGROUND: In this study, innovative chocolate, citrus and mixture flavoured tofu-based nutritionally customised, dysphagia-oriented, comfortably consumed, appetising, one-bite-sized finger foods, oriented to malnutrition, sarcopenia and frailty prevention in older people were created by using 3D printing technology. Developed products were characterised by evaluating chemical composition and physical properties and performing sensory evaluation among geriatric clinic residents (≥60 years). RESULTS: The dietary composition of the developed foods was: 19-21 g (100 g)-1 protein, 6-8 g (100 g)-1 fibre, 8-9 g (100 g)-1 fat, 11 mg (100 g)-1 iron, 14 mg (100 g)-1 zinc, 70 µg (100 g)-1 selenium. Foods were also enriched with branched-chain amino acids, such as leucine, isoleucine and valine. All formulated foods were classified as level 6 by International Dysphagia Diet Standardisation Initiative classification. Chocolate-flavoured food was much harder (4914 g) with lower adhesiveness value (-33.6 g s), compared to the citrus- or mixture-flavoured foods. Older people evaluated all finger foods as very easy handled by hand, soft, easy to swallow, having a moderate flavour intensity and a weak afterfeel. Despite the fact that the chocolate food was evaluated as having the highest hardness and gumminess values by the instrumental method, this difference was not noticeable to the evaluators. However 7% of the participants said that 3D printed foods were sticky to dentures. CONCLUSION: The results suggest that it is possible to create nutrient-dense comfortably consumed 3D printed foods, oriented to malnutrition, sarcopenia and frailty prevention in older people. © 2024 Society of Chemical Industry.

Oropharyngeal Dysphagia as the Main Expression of Amyotrophic Lateral Sclerosis.

Amyotrophic lateral sclerosis (ALS) is the most common form of motor neuron disease. Only about 10% of ALS patients survive more than 10 years. Clinical studies show that multidisciplinary care statistically significantly improves survival compared to neurological care. ALS tends to manifest as limb weakness, but some patients present with bulbar symptoms, such as dysphagia and dysarthria. In rarer cases, the main symptom of ALS is oropharyngeal dysphagia. Respiratory muscle weakness is a relatively rare symptom at the onset of this disease and may lead to a fatal outcome due to aspiration pneumonia within about 1.4 years. These reasons led to a particularly complicated diagnosis of ALS in a 66-year-old Caucasian female patient complaining of dyspnoea and coughing while drinking water. Notably, dyspnoea is only present in one out of four treatment-seeking patients, and the course of ALS is non-specific. For these reasons, the diagnosis took an entire year while the patient underwent many tests and visited many specialists. However, the diagnosis was only made at a late stage of the disease. At present, the patient is almost unable to swallow food, water, or saliva, and is at a very high risk of aspiration, but refuses to have a percutaneous endoscopic gastrostomy performed. The objective of this case report is to highlight the fact that a symptom as simple as difficulty swallowing may be the result of severe disease, a frequent outcome of which is death.

Formulating protein-based beverages for the dysphagia diets of the elderly: viscosity, protein quality, in vitro digestion, and consumers acceptability.

BACKGROUND: Dysphagia is defined as a disorder of the swallowing mechanism. The most common management of dysphagia is diet modification by thickening food and beverages. This study aimed to obtain protein-based beverages for the dysphagia diets of the elderly, corresponding to the 'honey' (III) level of dysphagia fluids according to the National Dysphagia Diet classifications, and containing 100 g kg-1 of good-quality proteins with a high rate of hydrolysis during digestion. RESULTS: Four protein formulations made from pea proteins, milk proteins, a mixture of milk and pea proteins, and milk proteins with added konjac glucomannan, were evaluated on the basis of rheological characterization and proteolysis kinetics during in vitro digestion. The mixture of milk proteins and pea proteins, and the mixture of milk proteins with added konjac glucomannan, showed typical yielding pseudoplastic fluid behavior with similar apparent viscosity but different structural characteristics. These differences were the reason for the differences in proteolysis kinetics during digestion. The mixture of milk and pea proteins showed viscous liquid behavior and was more rapidly hydrolyzed under gastrointestinal conditions than mixtures containing milk proteins and konjac glucomannan acting as a weak gel system. CONCLUSION: We presume that geriatric consumers with swallowing difficulties may benefit from 'honey'-level viscosity, protein-based beverages containing pea and milk proteins through faster proteolysis and better bioaccessibility of amino acids during digestion. © 2020 Society of Chemical Industry.

Discharge Planning and Home Care Needs Assessment for Older Patients in a Nursing Hospital.

Background and objectives: Following the accumulation of a sufficient amount of scientific evidence, it is now possible to appeal for changes in the organization of nursing services. Our aims are to assess the health status of patients discharged from nursing hospitals and to identify their home care needs by applying the international InterRAI Home Care (HC) assessment form. Material and methods: 152 geriatric patients (older than 65 years of age) discharged after a 90-120-day stay at a nursing hospital were examined using face-to-face interviews. The data from the medical records were also assessed. The capacities of patients were discussed with the patients themselves, nursing personnel, and relatives of the patients. Results: The analysis revealed that 45.4% of the respondents had severely impaired cognitive skills, while 27.6% had moderately impaired cognitive skills for decision making in daily living. People with greater cognitive difficulties were more dependent during daily instrumental activities and ordinary daily activities. The strongest relationship was established among the cognitive skills and management of medications, management of finances, and ordinary housework. For the greater part of respondents, a special need for permanent nursing (57.9%) or assistance (25.7%) was determined, i.e., official, state-funded nursing at home was appointed. The remaining respondents (16.4%) were not appointed further state-funded nursing or assistance at home, but an assessment of the independence of these patients based on the InterRai Activities of Daily Living Hierarchy Scale indicated that these skills varied from moderate independence (decision making was difficult only in new situations) to severely impaired skills (made no independent decisions or they were scarce). Despite the low independence of respondents, the majority of them would prefer nursing services at home to institutional nursing. Conclusions: The low independence observed in all participants, as well as their limited capacities, prove the need for nursing services at home and the necessity of their continuity. Despite the low independence of respondents, the majority of them would prefer nursing services at home to institutional nursing.

Older Adults-Potential Users of Technologies.

Background and objective: The successful adoption of technology is becoming increasingly important to functional independence and successful ageing in place. A better understanding of technology usage amongst older people may help to direct future interventions aimed at improving their healthcare. We aimed to obtain the first data regarding technology use, including gerontechnologies, represented by fall detectors, from older adults in Lithuania. Material and methods: The research was carried out in the framework of the project Smart Gerontechnology for Healthy Ageing, which involved assessing the use of technologies and the readiness to use gerontechnologies, as represented by fall detectors. A total of 375 individuals that were more than 60 years of age were enrolled in the study. The self-reporting questionnaires were completed by geriatric in-patients, hospitalized in the geriatric department, and also by community-dwelling older adults. Results: Geriatric in-patients' use of computers and the internet was associated with age (every year of age decreased the probability of computer and internet use by 0.9-times) and a positive attitude towards new technologies-this predictor increased the use of a computer by six-times in comparison with people who did not have such an attitude. Sex and education had no influence on computer use for geriatric in-patients. For community-dwelling older adults, the use of computers and internet was associated with age, education (a university education increased the use of computers and the internet by four times), and a positive attitude towards technologies. Conclusions: Lithuanian older women in the study used computers, the internet, and cell phones equally with men. Increasing age was a strong negative predictor of technology use. A positive attitude to new technologies was a strong positive predictor of technology use. Most geriatric patients and community-dwelling older adults were ready to use technologies that permit ageing in place.

Perioperative factors affecting length of hospital stay among elderly patients.

BACKGROUND AND OBJECTIVE: Timely assessment and prevention of risk factors for the main perioperative complications in elderly patients provide an opportunity to avoid them, decrease mortality, and diminish costs associated with longer hospital stay. The aim of this study was to estimate perioperative factors that could potentially predict the length of stay and to estimate their predictive value using a comprehensive geriatric assessment among elderly patients. MATERIAL AND METHODS: The study population comprised 99 surgical patients aged 65 and more. The patients were followed up until discharge. Study data analysis included questionnaires, anthropometric measurements before surgery, assessment and interviews after surgery, and case histories. Univariate and multivariate logistic regression analysis was performed. RESULTS: Malnutrition was detected in 53.5% of the patients. Postoperative cognitive disorder was documented in 18.2% of elderly patients. The mean length of hospital stay was 10.1 days (SD, 9.14). Multivariate logistic regression analysis revealed that the best predictors for longer hospital stay in elderly patients were malnutrition (OR, 4.2; 95% CI, 1.5-11.8; P=0.007) together with postoperative cognitive impairment (OR, 9.2; 95% CI, 1.0-83.3; P=0.048). The total predictive value of the model was 70.5%. CONCLUSIONS: . Malnutrition and a postoperative cognitive disorder were independent risk factors for longer hospital stay, while depression, cognitive impairment, functional dependence, and poor physical status were not independently associated with longer hospital stay. A comprehensive geriatric assessment can help assess the risk factors for longer treatment and predict the length of hospital stay, thus enabling the planning of optimal healthcare management of elderly patients.

Individualized care for older adults with diabetes and its relationship with communication, psychosocial self-efficacy, resources and support for self-management and socio-demographics.

AIM: To examine the relationship between patient-provider communication, psychosocial patient self-efficacy, resources and support for self-management and socio-demographics within individualized care of older adults with diabetes. DESIGN: A quantitative study with a cross-sectional survey design. METHODS: Data were collected from September 2019 to January 2021 using: Individualized Care Scale, The Communication Assessment Tool, The Diabetes Empowerment Scale and The Resources and Support for Self-Management Scale. Patients with either Type 1 or Type 2 diabetes mellitus that were 65 years old and over (N = 145) participated in the study. RESULTS: The most positive aspects of patient-provider communication were respect and creating a comfortable environment for the patient. A significant relationship was observed between patients' perceptions and support of individualized care and diabetes-related measures. Effective communication was the main factor associated with support for individualizing care, and together with education level, empowerment and access to resources, explained 23% of the variance.

Associations of the serotonin transporter gene polymorphism, 5-HTTLPR, and adverse life events with late life depression in the elderly Lithuanian population.

Late-life depression (LLD) is a multifactorial disorder, with susceptibility and vulnerability potentially influenced by gene-environment interaction. The aim of this study was to investigate whether the 5-HTTLPR polymorphism is associated with LLD. The sample of 353 participants aged 65 years and over was randomly selected from the list of Kaunas city inhabitants by Residents' Register Service of Lithuania. Depressive symptoms were ascertained using the EURO-D scale. The List of Threatening Events Questionnaire was used to identify stressful life events that happened over the last 6 months and during lifetime. A 5-HTTLPR and lifetime stressful events interaction was indicated by higher odds of depression in those with s/s genotype who experienced high stress compared to l/l carriers with low or medium stress, while 5-HTTLPR and current stressful events interaction analysis revealed that carriers of either one or two copies of the s allele had increased odds of depressive symptoms associated with stress compared to participants with the l/l genotype not exposed to stressful situations. Although no significant direct association was found between the 5-HTTLPR short allele and depression, our findings demonstrated that lifetime or current stressful life events and their modification by 5-HTTLPR genotype are risk factors for late-life depression.

Dementia with Lewy bodies: the principles of diagnostics, treatment, and management.

Dementia with Lewy bodies was first recognized as a separate entity about 30 years ago. The prevalence varies from 0% to 5% in the general population, and this disease accounts for 0% to 30.5% of all dementia cases. Dementia with Lewy bodies is considered the second most common cause of degenerative dementia after Alzheimer's disease. The disease is characterized by alpha-synuclein immunoreactive protein deposits in both neurons and glial cells. The protein deposits are especially prominent in dopaminergic neurons, where they can be detected using conventional histological stains, such as hematoxylin and eosin, and are commonly referred to as Lewy bodies. The diagnosis of dementia with Lewy bodies is based on the presence of dementia as well as 2 of the following 3 core diagnostic features: 1) fluctuating cognition, 2) visual hallucinations, and 3) movement disorder. Diagnostic tests include laboratory data, structural and functional imaging, and electroencephalography. Differential diagnosis of dementia with Lewy bodies focuses on other later life dementia syndromes, other parkinsonian diseases (Parkinson's disease, progressive supranuclear palsy, corticobasal degeneration), and primary psychiatric illnesses. There is type 1b evidence to support treatment with cholinesterase inhibitors. Glutamatergic and dopaminergic therapies are used as well. Standard neuroleptics are contraindicated, and atypical agents should be used cautiously. Nonpharmacologic measures - therapeutic environment, psychological and social support, physical activity, behavioral management strategies, caregivers' education and support, and different services - could be suggested.

Alzheimer's Disease Association with Metals and Metalloids Concentration in Blood and Urine.

As there is some evidence that the risk for Alzheimer's disease (AD) is partially attributable to environmental exposure to some metals and metalloids, we examined an association between AD and arsenic, chromium, and selenium in 53 AD patients and 217 controls. Urinary arsenic, blood chromium, and selenium were determined by inductively coupled plasma mass spectrometry. Logistic regression models calculating odds ratios (ORs) and 95% confidence intervals (CI) were used to estimate AD association with arsenic, chromium, and selenium. In AD patients, urinary arsenic and blood chromium were significantly higher, while blood selenium was significantly lower compared to controls. Increased blood selenium was related to a significant decrease in the odds of AD after adjustment for risk factors. Blood selenium per 1 kg × 10-9/m3 × 10-4 increment was associated with 1.4 times lower risk of AD (OR = 0.71; 95% CI 0.58-0.87). A significant increase in the odds of AD associated with increased blood chromium was also seen in the adjusted model: the OR per 1 kg × 10-9/m3 × 10-3 chromium increment was 2.39 (95% CI 1.32-4.31). The association of urinary arsenic with the risk of AD was not significant. The data obtained provide evidence that selenium reduces the risk of Alzheimer's disease, while chromium increases it.

Individualized Health Care for Older Diabetes Patients from the Perspective of Health Professionals and Service Consumers.

BACKGROUND: Individualized nursing care as a form of person-centered care delivery is a well-known approach in the health care context and is accepted as best practice by organizations and professionals, yet its implementation in everyday practice creates serious challenges. The aim was to assess and compare the perceptions of health professionals and older diabetes patients on their individual care in regard to the patient's clinical situation, personal life situation, and decisional control. METHODS: The quantitative study with a cross-sectional survey design was conducted from March 2019 until January 2021. The Individualized Care Scale was applied for the data collection. Health professionals (nurses and physicians, n = 70) and older diabetes patients (n = 145) participated in the study. The average duration of diabetes was 15.8 years (SD = 10.0) and type 2 diabetes was the most common (89.0%). The current glucose-lowering therapy for 51.0% of the patients was oral medications, 37.9% used injected insulin, and 11.1% were treated by combined therapy. RESULTS: The highest-rated aspects of individualized care on both dimensions of the scale from the health professionals' perspective related to the clinical situation, and the scores for provision were significantly higher than those for support. The highest means of patients' ratings on the support dimension related to the clinical situation and the decisions over care sub-scale; for the care provision dimension, the highest individuality in care was assigned to the decisions over care sub-scale. The lowest ratings of individualized care, both in the health professionals' and patients' samples, related to the personal life situation sub-scale. CONCLUSIONS: Health professionals are more positive in regard to individualized care support and provisions for older diabetes patients than the patients themselves. Patient characteristics, such as the type of glucose-lowering therapy, education, and nutritional status, make a difference in patients' understanding and experience of individuality in care.

Impaired Subjective Visual Vertical and Increased Visual Dependence in Older Adults With Falls.

Aging affects the vestibular system and may disturb the perception of verticality and lead to increased visual dependence (VD). Studies have identified that abnormal upright perception influences the risk of falling. The aim of our study was to evaluate subjective visual vertical (SVV) and VD using a mobile virtual reality-based system for SVV assessment (VIRVEST) in older adults with falls and evaluate its relationship with clinical balance assessment tools, dizziness, mental state, and depression level. This study included 37 adults >65 years who experienced falls and 40 non-faller age-matched controls. Three tests were performed using the VIRVEST system: a static SVV, dynamic SVV with clockwise and counter-clockwise background stimulus motion. VD was calculated as the mean of absolute values of the rod tilt from each trial of dynamic SVV minus the mean static SVV rod tilt. Older adults who experienced falls manifested significantly larger biases in static SVV (p = 0.012), dynamic SVV (p < 0.001), and VD (p = 0.014) than controls. The increase in static SVV (odds ratio = 1.365, p = 0.023), dynamic SVV (odds ratio = 1.623, p < 0.001) and VD (odds ratio = 1.460, p = 0.010) tilt by one degree significantly related to falls risk in the faller group. Fallers who had a high risk of falling according to the Tinetti test exhibited significantly higher tilts of dynamic SVV than those who had a low or medium risk (p = 0.037). In the faller group, the increase of the dynamic SVV tilt by one degree was significantly related to falls risk according to the Tinetti test (odds ratio = 1.356, p = 0.049). SVV errors, particularly with the dynamic SVV test (i.e., greater VD) were associated with an increased risk of falling in the faller group. The VIRVEST system may be applicable in clinical settings for SVV testing and predicting falls in older adults.

[Postoperative cognitive dysfunction of older surgical patients]. / Vyresnio amziaus pacientu pazinimo funkciju pooperacinis sutrikimas.

Light changes in mental function after operation occur in patients of all ages, but more frequent they are observed in older patients. The incidence of early postoperative cognitive dysfunction varies depending on surgical procedure and may be as high as 20-90% in aged patients, and occurs most often in patients undergoing cardiovascular surgery. Early postoperative cognitive dysfunction is a predictor of late postoperative cognitive dysfunction. Delirium develops in at least 50% of older surgical patients and even more frequently after cardiac surgeries (72%). Postoperative delirium, like delirium manifesting with co-existing disease, and late postoperative cognitive dysfunction are strong predictors of functional and cognitive decline in one-year period after discharge and are associated with higher morbidity and mortality, longer hospital stay, and a higher rate of institutionalization. The reasons of postoperative cognitive dysfunction and delirium are not well understood. An assessment of cognitive function should be completed as a routine in older patients, and effective prevention requires the identification of risk factors for delirium: advanced age, preexisting dementia and depression, visual and hearing impairment, Parkinson disease, emergency operation, anticholinergic drugs, and others. After operation, elderly patients must be carefully monitored for probable postoperative delirium. It is important to deepen health care professionals' knowledge of postoperative cognitive complications in older surgical patients.

[Use of technologies in maintaining autonomy of frail older persons]. / Technologiju pritaikymas pagyvenusio amziaus zmoniu savarankiskumui palaikyti.

Although Lithuanian population is aging and the number of older persons is increasing, the expectancy of autonomous life is one of the shortest in Europe. An increasing number of the elderly results not only in aging society, but in increasing morbidity as well. Reality of life is encouraging health care systems to take into account the needs of older patients and to seek for comprehensive assessment, which is not limited by physical assessment only but includes evaluation of functional state, cognition, socioeconomic status, home environment, identification of geriatric syndromes and vulnerability factors, and assessment of frailty. The term "frailty" is used to describe the status of the elderly person who can usually perform the main practical and social daily tasks, but due to loss of various functions, changes, or disorders cannot restore quickly the strength. Concomitant diseases, disorders, disability, and frailty were considered as synonyms, but the researchers have recently agreed that these terms are not the same. The social part of supportive environment is composed of people (family, friends, professional caregivers) who provide help. The physical part includes technologies that make living easier and more autonomous. Gerontechnologies in vulnerable and frail elderly people can compensate impaired orientation and memory, widen the possibility to communicate, exchange information, and move. With the help of gerontechnologies, safe home environment and monitoring of health state can be ensured. In the article, algorithm for maintenance of autonomy in older persons made by the authors is presented.

[Assessment of cognitive functions of the elderly in a hospital and long-term care institutions]. / Pagyvenusio amziaus zmoniu pazinimo funkciju ivertinimas stacionare ir ilgalaikes globos institucijose.

UNLABELLED: The aim of this study was to assess cognitive functions of the elderly in an acute care department and long-term care institutions. MATERIAL AND METHODS: A total of 151 hospitalized patients and 111 residents in long-term care facilities participated in the study; in total, 262 respondents. The general items of the inter RAI Questionnaires (Acute Care and Long-Term Care Facilities) were used to evaluate and compare cognitive functions. Hospitalized patients were examined on admission (during 24 hours) evaluating the patient's status before hospitalization (three days before admission to hospital) and 24 hours before planned discharge. The residents in long-term care institutions were examined once. RESULTS: The assessment of skills for daily decision-making showed that more patients made decisions independently at discharge (68.6%) comparing with admission day (53.0%). Impaired decision-making was more common on admission than at discharge, while the residents in long-term care institutions were more dependent than the hospitalized elderly. Procedural memory problems were more frequent among the residents in long-term care institutions (67.6%) than among the hospitalized elderly both on admission (34.7%) and discharge (21.9%) (P<0.001). The patients were able to express themselves clearly and understood others well at discharge more frequently (81.0% and 82.5%, respectively) than on admission (72.7% and 75.3%, respectively), while only 14.4% of the residents in long-term care institutions were able to express themselves clearly and understood others well (P<0.001). CONCLUSIONS: The residents in long-term care institutions had worse cognitive functions than the hospitalized patients. Cognitive functions of the hospitalized elderly were significantly more impaired on admission as compared to discharge, possibly due to impaired somatic and functional status on admission.

[Assessment of urinary incontinence in the elderly using the InterRAI-AC instrument]. / Pagyvenusio amziaus zmoniu slapimo nelaikymo tyrimas naudojant InterRAI-AC klausimyna.

UNLABELLED: The aim of this study was to identify and evaluate the prevalence of urinary incontinence and risk factors that influenced it among inpatients treated in the departments of internal medicine. MATERIAL AND METHODS: A total of 151 inpatients were questioned using a standardized geriatric questionnaire (InterRAI-Acute Care). Inpatients aged 65 years and more and who gave written informed consent were enrolled into the study. The mean age of the inpatients was 78+/-0.6 years. There were 58.9% of women and 41.06% of men. RESULTS: Urinary incontinence was significantly influenced by the age of the inpatients. Inpatients with urinary incontinence were 3 years older on the average as compared to those without urinary continence (P<0.025). Women were more frequently affected than men (74.2% vs. 48.4%). A significant association between urinary and fecal incontinence and memory problems, movement disorders, delirium, dependence in daily activities, falls was established. The odds of having double incontinence were increased by dementia (OR=20.9; 95%, CI 2.3-186) and residual effects of a stroke (OR=3.5; 95%, CI 1.2-9.6). The prevalence of urinary incontinence decreased from 63.6% before hospitalization to 39.7% after hospitalization. According to standard medical documentation, urinary incontinence was diagnosed in 3.3% of cases, while using the interRAI-AC questionnaire, it was documented in 63.6% of cases. CONCLUSIONS: The prevalence of urinary incontinence increases in the elderly; therefore, it has to be investigated and treated. Memory problems, delirium, dependence in daily activities, movement disorders, and falls are directly related to the risk of urinary, fecal, and double incontinence among elderly inpatients. Double incontinence was significantly influenced by dementia (20.9 times) and residual effects of a stroke (3.5 times). Underdiagnosis of urinary and fecal incontinence in inpatients burdens the possibility of providing aid for elderly patients with this disorder.

Off-Label Use of Antipsychotic Agents in Dementia: Evidence for the Revision of the Reimbursement Policy.

BACKGROUND: Harmonized requirements apply for the marketing authorization of medicinal products in the EU Member States. On the contrary, the national legislations on the drug reimbursement are not harmonized. The aim of this study was to find out if they are robust enough to ensure high standards of public health protection with focus on the symptomatic treatment of dementia in the elderly. METHODS: A computerized search of authorized therapeutic indications of haloperidol and trihexyphenidyl in the national databases of 8 EU member states and an analysis of the national legislation on reimbursement policies in Lithuania and Latvia was performed. RESULTS: There is a discrepancy in the decisions on the marketing authorization vs the reimbursement in Lithuania and Latvia (reimbursement of haloperidol and trihexyphenidyl for the off-label treatment of dementia). CONCLUSIONS: National legislation on the drug reimbursement in Lithuania and Latvia does not provide safeguards for public health at the same level as the marketing authorization does. Absence of a revision of former decisions in the light of new evidence is a critical weakness of the drug reimbursement in Lithuania and Latvia. Reimbursement for the off-label indications may pose a risk to public health.

[Nutritional status of elderly surgical patients]. / Pagyvenusio amziaus operuotinu pacientu mitybos bukle.

UNLABELLED: The aim of this study was to assess nutritional status of aged surgical patients, to determine the prevalence of malnutrition and factors associated with it. MATERIAL AND METHODS: A total of 156 patients aged 45 years and more, treated at the Departments of Surgery and Urology of Kaunas 2nd Clinical Hospital, were enrolled in the study. Elderly group (aged 65 years and more) consisted of 99 patients, and middle-aged group (45 to 64 years old) of 57 patients. The following anthropometric measurements were performed: weight, height, mid-arm circumference; hemoglobin, serum albumin level, and total lymphocyte count were determined. Standard assessment scales included Instrumental Activities of Daily Living, Geriatric Depression Scale, and Mini Mental State Exam. Statistical analysis was performed with the help of SPSS 12.0. RESULTS: Malnutrition was diagnosed in 53.5% of older patients and in 15.8% of middle-aged patients (P<0.05). Obesity was diagnosed in 32.3% of elderly patients and in 40.4% of middle-aged patients (P<0.05). Among men, obese patients made up 20%, among women - 54.4% (P<0.05). Malnutrition was more prevalent among elderly patients who underwent urgent operations than in patients who underwent planned operations (69.6% and 34.1%, respectively; P<0.05) and among elderly patients with impaired cognitive functions than among those without impaired cognitive functions (in 100% of patients with medium impaired cognitive function, in 59.3% of patients with mild impaired cognitive function, and in 44.4% of patients with unimpaired cognitive function, P<0.05). Malnourished elderly patients had lower functional level than the remaining (IADL score of 3.97 and 4.75 for men, 5.38 and 6.89 for women, respectively; P<0.05). The prevalence of malnutrition did not differ significantly in the groups of older patients with depression, probable depression and not depressed patients - 75.0%, 57.7%, and 46.7%, respectively (P>0.05). CONCLUSIONS: Malnutrition was diagnosed more frequently in elderly surgical patients than in middle-aged patients. Obesity was more common in women than in men. The prevalence of obesity was not associated with age. Malnutrition in elderly surgical patients was associated with poor functional status, impaired cognitive function, and urgent operation.

ABO blood group polymorphism has an impact on prostate, kidney and bladder cancer in association with longevity.

The aim of the present study was to assess the ABO blood group polymorphism association with prostate, bladder and kidney cancer, and longevity. The following data groups were analyzed: Prostate cancer (n=2,200), bladder cancer (n=1,530), renal cell cancer (n=2,650), oldest-old (n=166) and blood donors (n=994) groups. The data on the ABO blood type frequency and odds ratio in prostate cancer patients revealed a significantly higher blood group B frequency (P<0.05); the pooled men and women, separate men bladder cancer risk was significantly associated with the blood group B (P<0.04); however, no such association was identified in the female patients. The blood group O was observed to have a significantly decreased risk of bladder cancer for females (P<0.05). No significance for the ABO blood group type in the studied kidney cancer patients was identified. A comparison of the oldest-old and blood donor groups revealed that blood group A was significantly more frequent and blood type B was significantly rarer in the oldest-olds (P<0.05). The results of the present study indicated that blood type B was associated with the risk of prostate and bladder cancer, and could be evaluated as a determinant in the negative assocation with longevity. Blood types O and A may be positive factors for increasing the oldest-old age likelihood. The clustering analysis by the ABO type frequency demonstrated that the oldest-olds comprised a separate cluster of the studied groups.

SCARB1 rs5888 is associated with the risk of age-related macular degeneration susceptibility and an impaired macular area.

BACKGROUND: Age-related macular degeneration (ARMD), a progressive retinal disease, is responsible for an impaired central vision in about 180 million people worldwide. Current options for ARMD prevention and treatment are limited due to an incomplete understanding of disease etiopathogenesis. We aimed to test the hypothesis that the single nucleotide polymorphism rs5888 of SCARB1 gene reflecting lipid and antioxidant micronutrient metabolism pathways is associated with ARMD susceptibility and to evaluate if there is any relation between SCARB1 rs5888 and the macular lesion area. MATERIALS AND METHODS: The prospective case-control study included patients with ARMD (n = 215) and the reference group (n = 238) drawn from a random sample of the Lithuanian population (n = 1436). The genotyping test of SCARB1 rs5888 was carried out using the real-time polymerase chain reaction method. RESULTS: Regression analysis adjusted by gender and age demonstrated that SCARB1 rs5888 TT genotype significantly decreased the odds for ARMD development (OR: 0.61, 95%; CI: 0.380-0.981, p = 0.04). A smoking habit and leading an outdoor life are associated with larger macular lesion areas in ARMD patients (0.54 (0.00-39.06) vs. 3.09 (0.02-19.30) and 0.27 (0.00-34.57) vs. 0.75 (0.00-39.06), respectively). In late stage ARMD subjects with CT genotype, the macular lesion area was larger than in TT carriers (7.64 (0.49-39.06) mm2 vs. 5.02 (0.03-37.06) mm2, p = 0.006). CONCLUSIONS: SCARB1 rs5888 and environmental oxidative stress have a prominent role in ARMD susceptibility, early ARMD progression to advanced stage disease and even in the outcome of the disease-an area of macular lesion.
