European position paper on polypharmacy and fall-risk-increasing drugs recommendations in the World Guidelines for Falls Prevention and Management: implications and implementationFalls prevention and management in older adults is a critical global challenge. One of the key risk factors for falls is the use of certain medications. Therefore, to prevent medication-related falls, the following is recommended in the recent World Guidelines for Falls Prevention and Management: (1) assess for fall history and the risk of falls before prescribing potential fall-risk-increasing drugs (FRIDs), (2) use a validated, structured screening and assessment tool to identify FRIDs when performing a medication review, (3) include medication review and appropriate deprescribing of FRIDs as a part of the multifactorial falls prevention intervention, and (4) in long-term care residents, if multifactorial intervention cannot be conducted due to limited resources, the falls prevention strategy should still always include deprescribing of FRIDs. In the present statement paper, the working group on medication-related falls of the World Guidelines for Falls Prevention and Management, in collaboration with the European Geriatric Medicine Society (EuGMS) Task and Finish group on FRIDs, outlines its position on how to implement and execute these recommendations in clinical practice. Preferably, the medication review should be conducted as part of a comprehensive geriatric assessment to produce a personalized and patient-centered assessment. Furthermore, the major pitfall of the published intervention studies so far is the suboptimal implementation of medication review and deprescribing. For the future, it is important to focus on gaining which elements determine successful implementation and apply the concepts of implementation science to decrease the gap between research and practice.Copyright © 2023, The Author(s).

Becoming a physician for older patients: Exploring the professional identity formation of medical students during a nursing home clerkship. A qualitative studyBACKGROUND: To prepare medical students for the growing population of older patients, an appropriate professional identity formation is desirable. The community of practice of medical school is primarily hospital-based and disease-oriented which will lead to the development of a physician who is mainly focused on cure. This focus alone however is not always appropriate for older persons' health care. The aim of this study is to explore the influence of participating in a nursing home community of practice on the professional identity formation of medical students. METHOD(S): A qualitative study based on a constructivist research paradigm was conducted, using individual semi-structured, in-depth interviews and a visual narrative method (drawing) as a prompt. Thematic analysis was applied to structure and interpret the data. The study population consisted of fifth-year medical students participating in a six-week nursing home clerkship. Thirteen participants were purposefully sampled. The clerkship took place in nursing homes in the South-West of the Netherlands. RESULT(S): The medical students described the nursing home as the living environment of the patients. Actively participating in the patients' care and experiencing the daily life of the patients was meaningful for the physician the students want to become in five ways: (1) a physician with a complete picture; (2) a physician who is close; (3) a physician who is in dialogue; (4) a physician who is able to let go and (5) a physican who collaborates. CONCLUSION(S): Caring for older patients in the nursing home influences the professional identity formation of medical students. Patient-centeredness, personal, holistic and tailored care, approachability and collaboration are important characteristics in becoming a physician for older persons' health care. The context of this care provides relevant learning experiences for this development and the becoming of a physician in general.Copyright © 2023. The Author(s).

Sex-specific fall trajectories and associated self-reported risk factors: A prospective analysis of the 3-year 5-country DO-HEALTH trialOBJECTIVE: Few studies have explored specific trajectories or patterns of falls over time in older adults, and the role of sex and self-reported risk factors for these trajectories were overlooked. This study aimed to identify sex-specific fall trajectories over 3 years and the self-reported risk factors associated with each trajectory in European older adults., DESIGN: Observational analysis of DO-HEALTH, a double-blind, randomized controlled trial., SETTING AND PARTICIPANTS: Multicenter trial conducted in 7 European centers: Zurich, Basel, Geneva (Switzerland), Berlin (Germany), Innsbruck (Austria), Toulouse (France), and Coimbra (Portugal), including 2157 community-dwelling adults aged 70 years and older without major health events in the 5 years prior to enrollment, with sufficient mobility and good cognitive status., METHODS: Falls were recorded prospectively via phone calls and in-person assessments every 3 months over 3 years of follow-up. Group-based trajectory modeling was used to identify sex-specific trajectories based on the number of falls experienced over the follow-up, and penalized logistic regression models identified the self-reported risk factors most associated with each trajectory., RESULTS: A total of 1958 participants were included in this analysis (mean age: 74.9 years, 61.7% women). We identified a "lower fall trajectory" and a "higher fall trajectory" among women and a "lower fall trajectory" and an "increasing fall trajectory" among men. In women, living alone was the only self-reported risk factor associated with the higher fall trajectory. In men, living alone (marginal), as well as reporting fatigue, pain or discomfort, mobility issues, and higher self-rated health, were significantly associated with experiencing the increasing fall trajectory., CONCLUSIONS AND IMPLICATIONS: This study provides a comprehensive assessment of falls over 3 years, highlighting differences in fall patterns and associated self-reported risk factors between men and women. These findings may offer valuable insights for developing sex-specific fall risk prediction models and targeted fall prevention strategies. Copyright © 2025. Published by Elsevier Inc.

Investigating the impact of fluid status on the ultrasound assessment of muscle quantity and quality in the diagnosis of sarcopenia - A multidimensional cross-sectional studyBACKGROUND: Sarcopenia is a clinical manifestation of adverse ageing, characterised by progressive loss of muscle mass and function. Diagnosis requires assessment of muscle quantity and quality; ultrasound represents an emerging tool for this. However, ultrasound muscle assessment may be impacted by fluid balance. This is particularly important when assessing for acute sarcopenia in hospitalised patients, where fluid disturbance often occurs. The primary aim of this study was to characterise the impact of fluid status on ultrasound muscle assessment, such that this may be accounted for in sarcopenia diagnostics. METHOD(S): This Multidimensional Cross-sectional study involved 80 participants, who were inpatients at QEHB, a large UK tertiary centre. Fluid status was evaluated clinically and quantified using Bioelectrical Impedance Analysis (BIA). Muscle quantity was measured using Bilateral Anterior Thigh Thickness (BATT) with Rectus Femoris (RF) echogenicity used to assesses muscle adiposity and hence provide an inverse measure of muscle quality. RESULT(S): A significant positive correlation was found between fluid status, measured using BIA, and BATT as a measure of muscle quantity, in males (rs = 0.662, p < 0.001) and females (rs = 0.638, p < 0.001). A significant negative correlation was found between fluid status and RF echogenicity (rs=-0.448, p < 0.001). CONCLUSION(S): These findings demonstrate associations between fluid balance and ultrasound assessment of muscle quantity and quality. Given the emerging use of ultrasound muscle assessment in sarcopenia diagnosis, there is a need to account for this in clinical practice. Future research should focus on the development of a corrective equation allowing assessment of muscle quantity and quality which account for changes in fluid status, hence aiding accurate diagnosis of sarcopenia.Copyright © 2023.

Activin type I receptor polymorphisms and body composition in older individuals with sarcopenia - Analyses from the LACE randomised controlled trialBackground Ageing is associated with changes in body composition including an overall reduction in muscle mass and a proportionate increase in fat mass. Sarcopenia is characterised by losses in both muscle mass and strength. Body composition and muscle strength are at least in part genetically determined, consequently polymorphisms in pathways important in muscle biology (e.g., the activin/myostatin signalling pathway) are hypothesised to contribute to the development of sarcopenia. Methods We compared regional body composition measured by DXA with genotypes for two polymorphisms (rs10783486, minor allele frequency (MAF) = 0.26 and rs2854464, MAF = 0.26) in the activin 1B receptor (ACVR1B) determined by PCR in a cross-sectional analysis of DNA from 110 older individuals with sarcopenia from the LACE trial. Results Neither muscle mass nor strength showed any significant associations with either genotype in this cohort. Initial analysis of rs10783486 showed that males with the AA/AG genotype were taller than GG males (174+/-7cm vs 170+/-5cm, p = 0.023) and had higher arm fat mass, (median higher by 15%, p = 0.008), and leg fat mass (median higher by 14%, p = 0.042). After correcting for height, arm fat mass remained significantly higher (median higher by 4% padj = 0.024). No associations (adjusted or unadjusted) were seen in females. Similar analysis of the rs2854464 allele showed a similar pattern with the presence of the minor allele (GG/AG) being associated with greater height (GG/AG = 174+/-7 cm vs AA = 170 +/-5cm, p = 0.017) and greater arm fat mass (median higher by 16%, p = 0.023). Again, the difference in arm fat remained after correction for height. No similar associations were seen in females analysed alone. Conclusion These data suggest that polymorphic variation in the ACVR1B locus could be associated with body composition in older males. The activin/myostatin pathway might offer a novel potential target to prevent fat accumulation in older individuals.Copyright: © 2023 Bashir et al.

ACE I/D genotype associates with strength in sarcopenic men but not with response to ACE inhibitor therapy in older adults with sarcopenia: Results from the LACE trialBackground Angiotensin II (AII), has been suggested to promote muscle loss. Reducing AII synthesis, by inhibiting angiotensin converting enzyme (ACE) activity has been proposed as a method to inhibit muscle loss. The LACE clinical trial was designed to determine whether ACE inhibition would reduce further muscle loss in individuals with sarcopenia but suffered from low recruitment and returned a negative result. Polymorphic variation in the ACE promoter (I/D alleles) has been associated with differences in ACE activity and muscle physiology in a range of clinical conditions. This aim of this analysis was to determine whether I/D polymorphic variation is associated with muscle mass, strength, in sarcopenia or contributed to the lack of response to treatment in the LACE study. Methods Sarcopenic individuals were recruited into a 2x2 factorial multicentre double-blind study of the effects of perindopril and/or leucine versus placebo on physical performance and muscle mass. DNA extracted from blood samples (n = 130 72 women and 58 men) was genotyped by PCR for the ACE I/D polymorphism. Genotypes were then compared with body composition measured by DXA, hand grip and quadriceps strength before and after 12 months' treatment with leucine and/or perindopril in a cross-sectional analysis of the influence of genotype on these variables. Results Allele frequencies for the normal UK population were extracted from 13 previous studies (I = 0.473, D = 0.527). In the LACE cohort the D allele was over-represented (I = 0.412, D = 0.588, p = 0.046). This over-representation was present in men (I = 0.353, D = 0.647, p = 0.010) but not women (I = 0.458, D = 0.532, p = 0.708). In men but not women, individuals with the I allele had greater leg strength (II/ID = 18.00 kg (14.50, 21.60) vs DD = 13.20 kg (10.50, 15.90), p = 0.028). Over the 12 months individuals with the DD genotype increased in quadriceps strength but those with the II or ID genotype did not. Perindopril did not increase muscle strength or mass in any polymorphism group relative to placebo. Conclusion Our results suggest that although ACE genotype was not associated with response to ACE inhibitor therapy in the LACE trial population, sarcopenic men with the ACE DD genotype may be weaker than those with the ACE I/D or II genotype.Copyright © 2023 Rossios et al.

Optimizing pharmacotherapy and deprescribing strategies in older adults living with multimorbidity and polypharmacy: EuGMS SIG on pharmacology position paperInappropriate polypharmacy is highly prevalent among older adults and presents a significant healthcare concern. Conducting medication reviews and implementing deprescribing strategies in multimorbid older adults with polypharmacy are an inherently complex and challenging task. Recognizing this, the Special Interest Group on Pharmacology of the European Geriatric Medicine Society has compiled evidence on medication review and deprescribing in older adults and has formulated recommendations to enhance appropriate prescribing practices. The current evidence supports the need for a comprehensive and widespread transformation in education, guidelines, research, advocacy, and policy to improve the management of polypharmacy in older individuals. Furthermore, incorporating deprescribing as a routine aspect of care for the ageing population is crucial. We emphasize the importance of involving geriatricians and experts in geriatric pharmacology in driving, and actively participating in this transformative process. By doing so, we can work towards achieving optimal medication use and enhancing the well-being of older adults in the generations to come.Copyright © 2023, The Author(s).

Baseline nutritional status and in-hospital step count are associated with muscle quantity, quality, and function: Results of an exploratory studyThis exploratory study aimed to assess associations of baseline nutritional status and in-hospital step count with muscle quantity, quality, and function. Seventy-nine participants aged >=70 years (mean age 79.1 years, 44.3% female) were recruited (elective colorectal surgery, emergency abdominal surgery, and general medical patients with infections). Baseline nutrition (Mini Nutritional Assessment) and in-hospital step count (Fitbit Inspire devices) were assessed. Ultrasound quadriceps, bioelectrical impedance analysis, and physical function were assessed at baseline and 7 (+/-2) days and 13 (+/-1) weeks post-admission/post-operatively. Baseline nutritional status was associated with baseline rectus femoris ultrasound echogenicity (normal: 58.5, at risk: 68.5, malnourished: 81.2; p = 0.025), bilateral anterior thigh thickness (normal: 5.07 cm, at risk: 4.03 cm, malnourished: 3.05 cm; p = 0.021), and skeletal muscle mass (Sergi equation) (normal: 21.6 kg, at risk: 18.2 kg, malnourished: 12.0 kg; p = 0.007). Step count was associated with baseline patient-reported physical function (=900 44.5; p = 0.010). There was a significant interaction between nutrition, step count, and time for skeletal muscle mass (Janssen equation) (p = 0.022).

The effects of neuromuscular electrical stimulation on hospitalised adults: Systematic review and meta-analysis of randomised controlled trialsIntroduction: Neuromuscular electrical stimulation (NMES) is a treatment to prevent or reverse acquired disability in hospitalised adults. We conducted a systematic review and meta-analysis of its effectiveness. Method(s): We searched MEDLINE, EMBASE, Cumulative Index to Nursing & Allied Health (CINAHL) and the Cochrane library. Inclusion criteria: randomised controlled trials of hospitalised adult patients comparing NMES to control or usual care. The primary outcome was muscle strength. Secondary outcomes were muscle size, function, hospital length of stay, molecular and cellular biomarkers, and adverse effects. We assessed risk of bias using the Cochrane risk-of-bias tool. We used Review Manager (RevMan) software for data extraction, critical appraisal and synthesis. We assessed certainty using the Grading of Recommendations Assessment, Development and Evaluation tool. Result(s): A total of 42 papers were included involving 1,452 participants. Most studies had unclear or high risk of bias. NMES had a small effect on muscle strength (moderate certainty) (standardised mean difference (SMD) = 0.33; P 0.05). In total, 9% of participants reported undesirable experiences. The effects of NMES on length of hospital stay, and molecular and cellular biomarkers were unclear. Conclusion(s): NMES is a promising intervention component that might help to reduce or prevent hospital-acquired disability.Copyright © The Author(s) 2023.

Feasibility within-subject RCT of neuromuscular electrical stimulation; an Intervention to Maintain and improve neuroMuscular function during period of Immobility (IMMI)INTRODUCTION: Neuromuscular electrical stimulation (NMES) is a potentially effective intervention to improve outcomes after a fragility fracture, but its feasibility in this group has not been established., METHODS: A feasibility study was conducted in two phases: 1) in the hospital only, and 2) hospital, rehabilitation centres, and participants' homes. Patients with fragility fracture were randomised to receive NMES for 6 weeks/discharge either to the right or left leg, with the other leg serving as control. Patients who had no mobility issues had contraindications to NMES and were unable to give consent were excluded. NMES was applied to quadriceps and tibialis anterior muscles for 30 min, 3 days/week. Sessions were progressed to achieve 60 min, 5-7 days/week. Feasibility outcomes included participant characteristics, recruitment rate, tolerability, and number of NMES sessions. Clinical outcomes included muscle strength, and ADL at six months., RESULTS: Overall, 1052 patients were identified, of whom 113 (11%) were eligible, and 29 (3%) were recruited (median Clinical Frailty Score 3, median Barthel ADL score 93/100). The recruitment rate was 0.45/week in phase 1 and 0.9/week in phase 2. Fifty-three percent achieved the target of 24 NMES sessions. However, 5/29 withdrew due to intolerance of NMES. Leg muscle strength improved in both treated and untreated legs, with marginally greater improvement observed in the tibialis anterior of treated legs., CONCLUSION: Although it would be feasible to evaluate the specific effect of NMES in fragility fracture patients in a multi-centre trial using home-based NMES, this would be possible only in a minority of mildly frail fragility fracture patients with little premorbid disability.

Use of drugs with anticholinergic properties at hospital admission associated with mortality in older patients: A Danish nationwide register-based cohort studyBACKGROUND: Use of drugs with anticholinergic properties (DAP) has a negative impact on older people., OBJECTIVE: Our aim was to examine the association between DAP at hospital admission and mortality in older patients., PATIENTS AND METHODS: We performed a nationwide population-based cohort study including patients aged >= 65 years admitted to Danish geriatric medicine departments during 2005-2014. National health registers were used to link with individual-level data. Patients were followed to emigration, death, or study termination (31 December 2015). DAP was defined as medications included in the anticholinergic cognitive burden (ACB) scale, which assigns each DAP a score between 1 and 3. The individual ACB score was calculated and the number of DAP counted. We used Cox proportional-hazard regressions to estimate the crude and adjusted hazard ratios adjusting for age, activities of daily living, marital status, index admission period, BMI, and prior hospitalizations (model 1), and additionally Charlson Comorbidity Index (model 2)., RESULTS: We included 74,589 patients aged (median IQR]) 83 (77-88) years. Use of one or more DAP (62.5%) was associated with increased mortality compared with those with no use (p = 5 for 30-day (1.46 1.32-1.61] and 1.46 1.09-1.95]), 1-year (1.34 1.28-1.41] and 1.48 1.29-1.70]), and overall mortality (1.27 1.23-1.31] and 1.44 1.31-1.59]), respectively., CONCLUSIONS: Use of DAP at hospital admission is associated with short- and long-term mortality in geriatric patients. Deprescribing studies are warranted to study whether the impact on mortality can be attenuated. Copyright © 2021. The Author(s).

Development of a multivariable prognostic PREdiction model for 1-year risk of FALLing in a cohort of community-dwelling older adults aged 75 years and above (PREFALL)BACKGROUND: Falls are the leading cause of fatal and non-fatal injuries in older adults, and attention to falls prevention is imperative. Prognostic models identifying high-risk individuals could guide fall-preventive interventions in the rapidly growing older population. We aimed to develop a prognostic prediction model on falls rate in community-dwelling older adults. METHOD(S): Design: prospective cohort study with 12 months follow-up and participants recruited from June 14, 2018, to July 18, 2019. SETTING: general population. SUBJECTS: community-dwelling older adults aged 75+ years, without dementia or acute illness, and able to stand unsupported for one minute. OUTCOME(S): fall rate for 12 months. STATISTICAL METHODS: candidate predictors were physical and cognitive tests along with self-report questionnaires. We developed a Poisson model using least absolute shrinkage and selection operator penalization, leave-one-out cross-validation, and bootstrap resampling with 1000 iterations. RESULT(S): Sample size at study start and end was 241 and 198 (82%), respectively. The number of fallers was 87 (36%), and the fall rate was 0.94 falls per person-year. Predictors included in the final model were educational level, dizziness, alcohol consumption, prior falls, self-perceived falls risk, disability, and depressive symptoms. Mean absolute error (95% CI) was 0.88 falls (0.71-1.16). CONCLUSION(S): We developed a falls prediction model for community-dwelling older adults in a general population setting. The model was developed by selecting predictors from among physical and cognitive tests along with self-report questionnaires. The final model included only the questionnaire-based predictors, and its predictions had an average imprecision of less than one fall, thereby making it appropriate for clinical practice. Future external validation is needed. TRIAL REGISTRATION: Clinicaltrials.gov ( NCT03608709 ).

The facilitators and barriers to improving functional activity and wellbeing in people with dementia: A qualitative study from the process evaluation of Promoting Activity, Independence and Stability in Early Dementia (PrAISED)Background: The PRomoting Activity, Independence and Stability in Early Dementia (PrAISED) study delivered an exercise and functional activity programme to participants living with dementia. A Randomised Controlled Trial showed no measurable benefits in activities of daily living, physical activity or quality of life. Objective(s): To explore participants' responses to PrAISED and explain why an intervention that might be expected to have produced measurable health gains did not do so. Method(s): A process evaluation using qualitative methods, comprising interviews and researcher notes. Setting(s): Data were collected in participants' homes or remotely by telephone or videoconferencing. Sample: A total of 88 interviews were conducted with 44 participants living with dementia (n = 32 intervention group; n = 12 control group) and 39 caregivers. A total of 69 interviews were conducted with 26 therapists. Result(s): Participants valued the intervention as proactively addressing health issues that were of concern to them, and as a source of social contact, interaction, information and advice. Facilitators to achieving positive outcomes included perceiving progress towards desired goals, positive expectations, therapists' skills and rapport with participants, and caregiver support. Barriers included: cognitive impairment, which prevented independent engagement and carry-over between sessions; chronic physical health problems and intercurrent acute illness and injury; 'tapering' (progressively infrequent supervision intended to help develop habits and independent activity); and the COVID-19 pandemic. Conclusion(s): Self-directed interventions may not be appropriate in the context of dementia, even in the mild stages of the condition. Dementia-specific factors affected outcomes including caregiver support, rapport with therapists, availability of supervision, motivational factors and the limitations of remote delivery. The effects of cognitive impairment, multimorbidity and frailty overwhelmed any positive impact of the intervention. Maintenance of functional ability is valued, but in the face of inevitable progression of disease, other less tangible outcomes become important, challenging how we frame 'health gain' and trial outcomes.Copyright © 2023 The Author(s).

Updating the British Geriatrics Society recommended undergraduate curriculum in geriatric medicine: A curriculum mapping and nominal group technique studyBackground: medical education must adapt to meet the challenges and demands of an ageing population, ensuring that graduates are equipped to look after older patients with complex health and social care needs. Recommended curricula in geriatric medicine in the United Kingdom and Europe offer guidance for optimal undergraduate education in ageing. The UK version, written by the British Geriatrics Society (BGS), requires updating to take account of innovations in the specialty, changing guidance from the General Medical Council (GMC), and the need to support medical schools preparing for the introduction of the national Medical Licensing Assessment (MLA). Method(s): the BGS recommended curriculum was mapped to the most recent European curriculum (2014) and the MLA content map, to compare and contrast between current recommendations and nationally mandated guidance. These maps were used to guide discussion through a virtual Nominal Group Technique (NGT), including 21 expert stakeholders, to agree consensus on the updated BGS curriculum. Result(s): the curriculum has been re-structured into seven sections, each with 1-2 overarching learning outcomes (LOs) that are expanded in multiple sub-LOs. Crucially, the curriculum now reflects the updated GMC/MLA requirements, having incorporated items flagged as missing in the mapping stages. Conclusion(s): the combined mapping exercise and NGT have enabled appropriate alignment and benchmarking of the UK national curriculum. These recommendations will help to standardise and enhance teaching and learning around the care of older persons with complexity.Copyright © 2023 The Author(s).

Professional identity formation of medical students in relation to the care of older persons: A review of the literatureWith the growing population of older persons, medical students have to be well prepared for older persons' health care during medical school. Becoming a doctor is an interplay of building competencies and developing a professional identity. Professional identity formation of medical students is a relatively new educational concept in geriatric medical education. This review aims to explore the concept of professional identity formation of undergraduate medical students in relation to the care of older persons. Twenty-three peer-reviewed studies were included and summarized narratively. Patient-centeredness, caring and compassion, collaboration and holistic care are characteristics of the doctor's professional identity in relation to the care of older persons. Participating in the context of older persons' health care contributes to the becoming of a doctor in general. In this context, the building of relationships with older persons, participating in their lives and role models are important influencers of professional identity formation. Furthermore, the perceptions and expectations medical students have of future doctoring influence their feelings about the care of older persons. To prepare medical students for older persons' health care, professional identity formation seems to be a relevant educational concept.

ROBot-assisted physical training of older patients during acUte hospitaliSaTion-study protocol for a randomised controlled trial (ROBUST)Background : During hospitalisation, older patients spend most of their time passive in bed, which increases the risk of functional decline and negative adverse outcomes. Our aim is to examine the impact of robot-assisted physical training on functional status in older geriatric patients during acute hospitalisation. Method(s): This is a single-centre investigator-blinded placebo-controlled randomised controlled trial including geriatric patients aged >= 65 years, able to ambulate before hospitalisation, and with expected length of stay >= 2 days. In addition to standard physiotherapy treatment, the intervention group receive active robot-assisted resistance training and the control group passive robot-assisted sham training. Exclusion criteria are as follows: ambulation without assistance at the time of inclusion, known severe dementia, delirium, patients who have received less than three training sessions at discharge, terminal illness, recent major surgery/lower extremity fracture, conditions contradicting the use of training robot, lower extremity metastases, deemed unsuitable for robot-assisted training by a healthcare professional, or weight > 165 kg. The primary outcome is functional status assessed by change in Barthel Index-100 and 30-s chair stand test between inclusion and day of discharge. Secondary outcomes include functional status at 1- and 3-month follow-up, quality of life, depression, concern about falling, falls, cognition, qualitative interviews, need of homecare, discharge destination, readmissions, healthcare costs, sarcopenia, muscle quantity (bioimpedance), and mortality. Clinical meaningful change of the Barthel Index is 5 points. A recent study in geriatric patients reported a 6.9-point change following exercise. With a significance level of 5%, 80% power, and a drop-out rate of 20%, 244 participants per group (n = 488) are needed to detect the same mean difference. With a significance level of 5%, 80% power, and a drop-out rate of 20%, 74 participants per group (n = 148) are needed to detect a minimum clinical change of 2.6 repetitions for 30-s chair stand test. Recruitment started in January 2023 and is expected to continue for 19 months including follow-up. Discussion(s): If our study shows that in-hospital robot-assisted training prevents functional decline in older patients, this may have a major impact on the individual patient due to increased wellbeing and a higher level of independency. In addition, society will benefit due to potential decrease in the need of municipality-delivered homecare following discharge. Trial registration: ClinicalTrials.gov NCT05782855.

Systematic review: Mortality associated with raised faecal immunochemical test and positive faecal occult blood resultsBackground: Faecal haemoglobin (f-Hb) testing is used in colorectal cancer (CRC) screening and increasingly to guide the investigation in patients with symptoms suggestive of CRC. Studies have demonstrated increased mortality with raised f-Hb. Aim(s): To assess the association of raised f-Hb with all-cause, non-CRC (any cause excluding CRC) and cause-specific mortality. Method(s): We searched Medline and Embase on 9 February 2024 to identify papers reporting mortality after faecal immunochemical (FIT) or guaiac faecal occult blood tests (gFOBT). The primary outcome was all-cause mortality following a positive compared to a negative test. Result(s): The search identified 3155 papers. Ten met the inclusion criteria: three reported gFOBT and seven reported FIT results, as screening tests. These reported a total of 14,687,625 f-Hb results. Elevated f-Hb was associated with an increased risk of all-cause, non-CRC and cause-specific mortality including death from cardiovascular, digestive and respiratory diseases. Crude risk ratios for all-cause mortality with a positive versus negative test were derived from six papers (three reporting gFOBT, three FIT). An increased risk was demonstrated in five, with RRs ranging from 1.11 (95% CI: 1.06-1.16) to 2.95 (95% CI: 2.85-3.05). For non-CRC mortality risk, RRs ranged from 1.09 (95% CI: 1.04-1.15) to 2.79 (95% CI: 2.70-2.89). We did not perform meta-analysis due to a limited number of papers reporting suitable results for each type of f-Hb test. Conclusion(s): All-cause, non-CRC and cause-specific mortality appear higher in those with raised f-Hb. Population-based studies are warranted to elicit whether this association occurs in symptomatic patients.Copyright © 2024 The Author(s).

Mapping the human genetic architecture of COVID-19The genetic make-up of an individual contributes to the susceptibility and response to viral infection. Although environmental, clinical and social factors have a role in the chance of exposure to SARS-CoV-2 and the severity of COVID-191,2, host genetics may also be important. Identifying host-specific genetic factors may reveal biological mechanisms of therapeutic relevance and clarify causal relationships of modifiable environmental risk factors for SARS-CoV-2 infection and outcomes. We formed a global network of researchers to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity. Here we describe the results of three genome-wide association meta-analyses that consist of up to 49,562 patients with COVID-19 from 46 studies across 19 countries. We report 13 genome-wide significant loci that are associated with SARS-CoV-2 infection or severe manifestations of COVID-19. Several of these loci correspond to previously documented associations to lung or autoimmune and inflammatory diseases3-7. They also represent potentially actionable mechanisms in response to infection. Mendelian randomization analyses support a causal role for smoking and body-mass index for severe COVID-19 although not for type II diabetes. The identification of novel host genetic factors associated with COVID-19 was made possible by the community of human genetics researchers coming together to prioritize the sharing of data, results, resources and analytical frameworks. This working model of international collaboration underscores what is possible for future genetic discoveries in emerging pandemics, or indeed for any complex human disease.Copyright © 2021, The Author(s).

Elective cancer surgery in COVID-19-free surgical pathways during the SARS-CoV-2 pandemic: An international, multicenter, comparative cohort studyPURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19-free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19-free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19-free surgical pathways. Patients who underwent surgery within COVID-19-free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19-free surgical pathways (2.2% v 4.9%; adjusted odds ratio aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score-matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19-free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19-free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks.Copyright © 2020 American Society of Clinical Oncology.
