Outcomes after laparoscopic cholecystectomy in patients older than 80 years: two-years follow-up

BACKGROUND

The laparoscopic cholecystectomy is the treatment of choice for patients with benign biliary disease. It is necessary to evaluate survival after laparoscopic cholecystectomy in patients over 80 years old to determine whether the long-term mortality rate is higher than the reported recurrence rate. If so, this age group could benefit from a more conservative approach, such as antibiotic treatment or cholecystostomy. Therefore, the aim of this study was to evaluate the factors associated with 2 years survival after laparoscopic cholecystectomy in patients over 80 years old.

METHODS

We conducted a retrospective observational cohort study. We included all patients over 80 years old who underwent laparoscopic cholecystectomy. Survival analysis was conducted using the Kaplan‒Meier method. Cox regression analysis was implemented to determine potential factors associated with mortality at 24 months.

RESULTS

A total of 144 patients were included in the study, of whom 37 (25.69%) died at the two-year follow-up. Survival curves were compared for different ASA groups, showing a higher proportion of survivors at two years among patients classified as ASA 1-2 at 87.50% compared to ASA 3-4 at 63.75% (p = 0.001). An ASA score of 3-4 was identified as a statistically significant factor associated with mortality, indicating a higher risk (HR: 2.71, CI95%:1.20-6.14).

CONCLUSIONS

ASA 3-4 patients may benefit from conservative management due to their higher risk of mortality at 2 years and a lower probability of disease recurrence.

Protocol of the MOVI-ageing randomized controlled trial: a home-based e-Health intervention of cognitively demanding exercise for the improvement of cardiorespiratory fitness and cognitive function in older individuals

Objective

To describe the protocol of the MOVI-ageing randomized controlled trial, a home-based eHealth intervention of cognitive-demanding exercise for older adults, in improving global cognitive function and basic cognitive functions, cardiorespiratory fitness, and muscle fitness.

Methods

This randomized controlled trial will include participants identified in the social centers of Cuenca and Talavera de la Reina who agree to participate and provide informed consent. Adults aged 60-80 years of both genders retired regardless of the reason for retirement, who do not meet frailty criteria according to Fried criteria, and without cognitive impairment will be invited to participate. This study will be developed in two phases: (i) a 12-week randomized efficacy/feasibility trial and (ii) a large-scale implementation randomized trial phase with a 12-week follow-up following similar procedures. In addition, a qualitative study on barriers to and facilitators of the implementation of the physical exercise intervention using eHealth for older people will be conducted. Participants will have access to a platform including videos of cognitively demanding physical exercise. The participants will be remotely and off-line guided through the physical exercise intervention, and the research team will be able to check the degree of compliance with the program and its correct execution. The participants will receive feedback on their compliance with the routines and reinforcement messages.

Implications

The implementations of the findings and their inclusion in guidelines may directly impact in older people's life, and relatives, through the prevention of morbidity and the reduction of years lost to disability. These benefits may be reflected in the reduction of economic expenditure by reducing the demand for social and health care services.

Ethics

The Clinical Research Ethics Committee of the 'Virgen de la Luz' Hospital in Cuenca approved the study protocol (registration number: 2022/PI3222). In addition, this protocol was previously registered in Clinicaltrials.gov (Number: NCT05928078).

Oral health and self-rated health in community-dwelling older adults in Colombia

BACKGROUND

The relationship between oral health and specific health conditions, such as cardiovascular disease or cognitive impairment, has been extensively studied. However, the effect of oral health status on self-rated health has not been assessed. This could be relevant in older people considering that poor self-rated health status and oral diseases are highly prevalent in this population. The aim of this study was to determine the association between different parameters of oral health and self-rated health status (SRHS) in Colombian community-dwelling older adults.

METHODS

This is a secondary analysis of the SABE-Colombia study performed in 2015. The dependent variable was defined as the SRHS status assessed by the question "Compared with other people, your age: Do you consider your health status to be better, equal, or worse?" We considered four independent variables: total edentulism considering the high prevalence in older people, the GOHAI score to assess self-rated oral health, and the use of fixed and removable dental prostheses as potential modifiers of oral health. An adjusted ordinal logistic regression was performed by each independent variable.

RESULTS

After the exclusion of missing data, 17,945 persons were included in the final analysis. A total of 10.6% reported worse SRHS, 37.6% reported equal SRHS, and 51.6% reported better SRHS. The worse SRHS group was older and had a higher proportion of dependence, cognitive impairment, and depressive symptoms. The frequency of total edentulism and the lower mean score of GOHAI were significant in the worse SHRS group. An ordinal logistic regression for each independent variable was performed, finding that edentulism increases the probability of worse SHRS, while the GOHAI and use of removable or fixed dental prostheses increase the probability of better SRHS.

CONCLUSION

We found an association between total edentulism, GOHAI Index, the use of dental prostheses (both removable and fixed), and self-rated health status, showing the relevance of oral health status to self-rated health status independent of comorbidities and geriatric syndromes. This result supports the inclusion of oral health evaluation in comprehensive geriatric assessment.

Clinical value of Hospital Admission Risk Profile (HARP) and the Identification of Seniors at Risk (ISAR) scales to predict hospital-associated functional decline in an acute geriatric unit in Colombia

Background

Older adults admitted to a hospital for acute illness are at higher risk of hospital-associated functional decline during stays and after discharge.

Objective

This study aimed to assess the calibration and discriminative abilities of the Hospital Admission Risk Profile (HARP) and the Identification of Seniors at Risk (ISAR) scales as predictors of hospital-associated functional decline at discharge in a cohort of patients older than age 65 receiving management in an acute geriatric care unit in Colombia.

Methods

This study is an external validation of ISAR and HARP prediction models in a cohort of patients over 65 years managed in an acute geriatric care unit. The study included patients with Barthel index measured at admission and discharge. The evaluation discriminate ability and calibration, two fundamental aspects of the scales.

Results

Of 833 patients evaluated, 363 (43.6%) presented hospital-associated functional decline at discharge. The HARP underestimated the risk of hospital-associated functional decline for patients in low- and intermediate-risk categories (relation between observed/expected events (ROE) 1.82 and 1.51, respectively). The HARP overestimated the risk of hospital-associated functional decline for patients in the high-risk category (ROE 0.91). The ISAR underestimated the risk of hospital-associated functional decline for patients in low- and high-risk categories (ROE 1.59 and 1.11). Both scales showed poor discriminative ability, with an area under the curve (AUC) between 0.55 and 0.60.

Conclusions

This study found that HARP and ISAR scales have limited discriminative ability to predict HAFD at discharge. The HARP and ISAR scales should be used cautiously in the Colombian population since they underestimate the risk of hospital-associated functional decline and have low discriminative ability.

Nutrition-Focused Care for Community-Living Adults: Healthcare Utilization and Economic Benefits

OBJECTIVES

We assessed the impact of a recently reported nutritional quality improvement program (QIP) on healthcare resource utilization and costs for older, community-living adults in Bogotá, Colombia.

METHODS

The study included 618 community-dwelling, older adults (> 60 years) who were at risk or malnourished and receiving outpatient clinical care. The intervention was a QIP that emphasized nutritional screening, dietary education, lifestyle counseling, 60-day consumption of oral nutritional supplements, and 90-day follow-up. For economic modeling, we performed 90-day budget impact and cost-effectiveness analyses from a Colombian third-party payer perspective. The base-case analysis quantified mean healthcare resource use in the QIP study population. Analysis was based on mean input values (deterministic) and distributions of input parameters (probabilistic). As the deterministic analysis provided a simple point estimate, the cost-effectiveness analysis focused on the probabilistic results informed by 1000 iterations of a Monte-Carlo simulation.

RESULTS

Results showed that the total use of healthcare resources over 90 days was significantly reduced by > 40% (hospitalizations were reduced by approximately 80%, emergency department visits by > 60%, and outpatient clinical visits by nearly 40%; P < .001). Based on economic modeling, total cost savings of $129 740 or per-patient cost savings of $210 over 90 days could be attributed to the use of nutritional QIP strategies. Total cost savings equated to nearly twice the initial investment for QIP intervention; that is, the per-dollar return on investment was $1.82.

CONCLUSIONS

For older adults living in the community in Colombia, the use of our nutritional QIP improved health outcomes while lowering costs of healthcare and was thus cost-effective.

Effect of multicomponent exercise in cognitive impairment: a systematic review and meta-analysis

Background

Multicomponent physical exercise is the most recommended type of physical intervention in older adults. Experimental data suggest the relevance of the muscle-brain axis and the relationship between muscle contraction and release of brain-derived neurotrophic factor, however, the impact of this relationship on cognition remains unclear, especially in people with diagnosis of cognitive impairment. This study assesses the effect of multicomponent physical exercise on global cognition in people with mild cognitive impairment or dementia.

Methods

Randomized controlled trials published until January 2021 were searched across three electronic databases (PubMed, Scopus, and Cochrane Database). Data about exercises included in the multicomponent intervention (endurance, strength, balance, or flexibility), the inclusion of aerobic exercise, and the change in global cognition were extracted. The effect size was represented as a standardized mean difference. Risk of bias was assessed by the RoB2 tool.

Results

A total of 8 studies were included. The overall effect size suggested an effect of multicomponent exercise on global cognition. However, the subgroup analysis showed an effect only when aerobic exercise was included in the intervention. No effect when mild cognitive impairment and dementia were assessed separately was found.

Conclusion

This study suggests that multicomponent physical exercise could have an effect on global cognition in people with mild cognitive impairment or dementia only when aerobic exercise is included in the intervention. Our results support the inclusion of structured physical exercise programs in the management of people with cognitive impairment.

Nutrition Program Improves Health-Related Outcomes of Non-Diabetic Elderly at Nutritional Risk

Malnutrition or its risk affects up to 1 in 3 older adults receiving outpatient care post a hospitalization or for chronic disease management. Although malnutrition poses a negative burden on someone’s recovery and health preservation, it can be effectively addressed through cost-effective nutrition interventions delivered as comprehensive quality improvement programs (QIPs) aiding to advance healthcare professional’s nutrition education/training and improve quality of care for at-risk/malnourished individuals. Although evidence from US and Europe demonstrates nutrition-focused QIPs are effective in delivering high-quality nutrition care and improve health outcomes of outpatients at-risk/malnourished, to date, no evidence has been reported from Latin American countries. We assessed effectiveness of a comprehensive, nutrition-focused QIP in a Colombian outpatient clinic. Between 09/2019-03/2020, 504 (of total 618) QIP participants were classified at-risk/malnourished and non-diabetics. Participants were followed for 90-days either in-person or via telehealth mechanisms (during COVID-19-imposed lockdown period). QIP interventions included healthcare professional nutrition education; QIP participant continuous nutrition and exercise counselling and 60-day supply of oral nutrition supplement (Ensure®, Abbott). QIP participants were 69% female, with >2 comorbidities, and mean age of 73. Improvement or maintenance of good mental health/well-being, frailty status, cognition and quality of life was reported for 90.7% (456/503), 87.3% (407/466), 86.7% (405/467) and 47% (237/504) participants, respectively (p-values<0.05). Results support QIP effectiveness in driving improved health-related outcomes for non-diabetic, at-nutritional-risk participants. These findings highlight the importance of nutrition-focused QIPs with ONS for older adults during their recovery phase post a recent hospitalization and/or for chronic disease management.

Effect of physical activity on cognitive domains in dementia and mild cognitive impairment: overview of systematic reviews and meta-analyses

OBJECTIVE

To assess the effect of physical activity on cognitive domains in persons with dementia or mild cognitive impairment.

DESIGN

An overview of systematic reviews and meta-analyses of randomized controlled trials were performed.

METHODS

A literature search was performed in PubMed, Scopus, and Cochrane Database of Systematic Reviews databases up to February 2020. Data about the change in cognitive domains after physical activity intervention was extracted and plotted.

RESULTS

We included 11 meta-analyses in this overview. The most frequent type of physical activity for the intervention group was the aerobic exercise with a duration between 6 and 78 weeks. Global cognition was the most common form of assessing the cognitive function, follow of executive function, delayed recall, attention, and verbal fluency. We found a positive effect of physical activity on global cognition, executive function, and delayed recall, but no effect on verbal fluency, attention, and immediate recall.

CONCLUSION

Physical activity shows a positive effect on cognition in people with dementia and mild cognitive impairment, especially when it was assessed as global cognition. Positive effects on executive function and memory were also shown. This result confirms the relevance of physical activity in the treatment of persons with cognitive impairment.

Association of Malnutrition with Functional and Cognitive Trajectories in People Living with Dementia: A Five-Year Follow-Up Study

BACKGROUND

In dementia, functional status depends on multiple factors in addition to cognition. Nutritional status is a potentially modifiable factor related to homeostasis and proper functioning of body systems and may contribute to cognitive and functional decline.

OBJECTIVE

This paper aims to analyze the association of malnutrition with the course of cognitive and functional decline in people living with dementia.

METHODS

This is an analysis of a longitudinal cohort study, the Dementia Study of Western Norway. Data of 202 patients diagnosed with mild dementia were analyzed; Alzheimer's disease (AD) (n = 103), Lewy body dementia (LBD) (n = 74), and other dementias (OD) (n = 25). Cognition was assessed with the Mini-Mental State Examination and functional decline through the activities of daily living included in the Rapid Disability Rating Scale. The Global Leadership Initiative on Malnutrition Index was used to determine nutritional status. Associations of nutritional status with cognitive and functional decline were evaluated through adjusted linear mixed models.

RESULTS

At baseline, the prevalence of general malnutrition was 28.7%; 17.3% were classified as moderate malnutrition and 11.38% as severe malnutrition (there were no significant differences between AD and LBD). Malnutrition at diagnosis and over follow-up was a significant predictor of functional-decline, but not of cognitive decline.

CONCLUSION

According to our results malnutrition was associated with faster functional loss but, not cognitive decline in older adults with dementia. A more comprehensive dementia approach including nutritional assessments could improve prognosis.

Body mass index, performance on activities of daily living and cognition: analysis in two different populations

BACKGROUND

With this study, we aim to determine the associations of the different categories of the body mass index (BMI) with activities of daily living (ADL) and cognitive performance in two different populations living in the community; Colombian and South Korean older adults.

METHODS

We performed a cross-sectional analysis of two surveys separately; The Survey on Health, Well-Being, and Aging in Colombia (SABE) (n = 23,343) and the Korean Longitudinal Study of aging (KLoSA) (n = 4556). Participants older than 50 years were selected from rural and urban areas achieving a representative sample. Here we investigated the association between BMI categories with function using zero-inflated negative binomial regressions, and with cognition using logistic regression models.

RESULTS

After adjustment, in Colombia, underweight was associated with an impaired score on the Mini-mental State Examination (MMSE) and worse performance in the instrumental activities of daily living (IADL). Also, being overweight was associated with a better score on the MMSE and the IADL. For both outcomes education level significantly influenced the predictions. In South Korea, there were no significant associations for cognition, IADL, or basic activities of daily living (BADL).

CONCLUSIONS

In the Colombian population, underweight, was associated with reduced cognitive performance and daily functioning. Additionally, being overweight but not obese was associated with better cognition and daily functioning. In South Korea, there were no significant associations between BMI and cognition, IADL, or BADL.

Linfopenia y riesgo de infecciones nosocomiales en ancianos en una institución de salud de Bogotá, Colombia. Estudio de casos y controles

Objetivo: La linfopenia se ha propuesto como un potencial factor asociado al riesgo de infecciones bacterianas nosocomiales (infección urinaria y neumonía), pero la magnitud y relevancia de este factor no ha sido evaluada formalmente. El objetivo de este estudio es determinar si existe asociación entre linfopenia e infecciones nosocomiales en ancianos hospitalizados en una institución de salud en Bogotá, Colombia. Métodos: Estudio de casos y controles, incluyendo personas mayores de 65 años hospitalizadas en el Hospital Universitario San Ignacio entre junio de 2016 y diciembre de 2017. Se consideraron casos aquellos con diagnóstico de infección nosocomial (neumonía, infección de vías urinarias, bacteriemia, infección de tejidos blandos) y se compararon con controles sin infección emparejados por edad y sexo. Se evaluó la asociación entre linfopenia e infección nosocomial mediante análisis bivariado y multivariado controlando por las variables de confusión. Resultados: Se incluyeron un total de 198 pacientes (99 casos y 99 controles). La prevalencia de linfopenia fue de 34.8%, sin encontrarse diferencia entre los dos grupos (p=0.88). La infección nosocomial se asoció a mayor incidencia de mortalidad (29.3 vs 10.1%, p>0.001) y mayor duración de estancia hospitalaria (Mediana 18 vs 9 días, p<0.01). Se encontró asociación entre infección nosocomial con enfermedad cardiovascular (OR = 2.87; IC 95% 1.37-6.00) y antecedente de cáncer (OR = 6.00; IC 95% 1.28-29.78), sin embargo, no hubo asociación con linfopenia (OR = 1.27; IC 95% 0.61-2.65). Conclusiones: Este estudio sugiere que no existe asociación entre linfopenia y el desarrollo de infecciones nosocomiales en pacientes ancianos.
