A novel prosthesis presentation test to screen for cognitive and functional decline.

OBJECTIVES AND BACKGROUND: To validate a novel screening test for cognitive and functional decline in older patients rehabilitated with complete removable dental prostheses (CRDPs). MATERIALS AND METHODS: Edentate old in-patients rehabilitated with CRDPs were included in this study. Participants were requested to remove their prostheses before their intraoral examinations. The prostheses were then presented in an inverted orientation. Participants had to correct the orientation of the prostheses and insert them in the appropriate jaws. The test was repeated after the intraoral exam. Appropriate statistical models were used (⍺ = .05) to associate the test results with the participants' mini-mental state examination (MMSE) score, functional independence measure (FIM), age and sex. RESULTS: Among the 86 participants (mean-age: 85.4 ± 6.4 years; mean MMSE: 19.8 ± 5.5; mean FIM: 77.9 ± 20.8), 21 (24.4%) failed to correctly insert the prosthesis. The prosthesis presentation test (PPT) was associated with the FIM but not the MMSE. Regression models further confirmed an association with age (P = .043), but not sex. Additional analyses revealed the PPT test is associated with the FIM's cognitive sub-sets of memory, problem solving and social interaction. CONCLUSION: The PPT is a novel, simple and quick screening tool that can help detect functional difficulties in older people. It can easily be performed during an oral examination. Future studies are needed to determine whether the PPT can be used to detect deficits in executive function, as a complement to the MMSE and also as a first assessment of a patient's ability to manage dentures independently.

Drug-induced hypersensitivity syndrome with lupus manifestations due to mesalazine in a patient with ulcerative colitis.

Mesalazine is often used as first-line therapy for ulcerative colitis. Several reports have pointed to systemic adverse reactions associated with this drug. Most have evoked a drug-induced hypersensitivity syndrome, while some have described lupus syndromes but with limited clinical and varied biological features. A 75-year-old man presented with fever, dyspnoea, chest pain, polyarthralgia, and myalgia, following mesalazine introduction. Clinical symptoms and low-titre positive antihistone antibodies disappeared after mesalazine withdrawal without recourse to steroids. Pericardial effusion and 8F-fluorodeoxyglucose uptake on positron emission tomography/CT scan, and glomerular haematuria and proteinuria also disappeared. Cytokine-lymphocyte transformation tests showed a strong sensitisation pattern with interleukin-5 production. This case advances our knowledge of the mechanism of mesalazine-induced adverse effects, namely via drug-induced hypersensitivity with lupus manifestations, which we are the first to report.

Deep learning diagnostic and risk-stratification pattern detection for COVID-19 in digital lung auscultations: clinical protocol for a case-control and prospective cohort study.

BACKGROUND: Lung auscultation is fundamental to the clinical diagnosis of respiratory disease. However, auscultation is a subjective practice and interpretations vary widely between users. The digitization of auscultation acquisition and interpretation is a particularly promising strategy for diagnosing and monitoring infectious diseases such as Coronavirus-19 disease (COVID-19) where automated analyses could help decentralise care and better inform decision-making in telemedicine. This protocol describes the standardised collection of lung auscultations in COVID-19 triage sites and a deep learning approach to diagnostic and prognostic modelling for future incorporation into an intelligent autonomous stethoscope benchmarked against human expert interpretation. METHODS: A total of 1000 consecutive, patients aged ≥ 16 years and meeting COVID-19 testing criteria will be recruited at screening sites and amongst inpatients of the internal medicine department at the Geneva University Hospitals, starting from October 2020. COVID-19 is diagnosed by RT-PCR on a nasopharyngeal swab and COVID-positive patients are followed up until outcome (i.e., discharge, hospitalisation, intubation and/or death). At inclusion, demographic and clinical data are collected, such as age, sex, medical history, and signs and symptoms of the current episode. Additionally, lung auscultation will be recorded with a digital stethoscope at 6 thoracic sites in each patient. A deep learning algorithm (DeepBreath) using a Convolutional Neural Network (CNN) and Support Vector Machine classifier will be trained on these audio recordings to derive an automated prediction of diagnostic (COVID positive vs negative) and risk stratification categories (mild to severe). The performance of this model will be compared to a human prediction baseline on a random subset of lung sounds, where blinded physicians are asked to classify the audios into the same categories. DISCUSSION: This approach has broad potential to standardise the evaluation of lung auscultation in COVID-19 at various levels of healthcare, especially in the context of decentralised triage and monitoring.

Predictors of In-Hospital Mortality in Older Patients With COVID-19: The COVIDAge Study.

OBJECTIVE: To determine predictors of in-hospital mortality related to COVID-19 in older patients. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: Patients aged 65 years and older hospitalized for a diagnosis of COVID-19. METHODS: Data from hospital admission were collected from the electronic medical records. Logistic regression and Cox proportional hazard models were used to predict mortality, our primary outcome. Variables at hospital admission were categorized according to the following domains: demographics, clinical history, comorbidities, previous treatment, clinical status, vital signs, clinical scales and scores, routine laboratory analysis, and imaging results. RESULTS: Of a total of 235 Caucasian patients, 43% were male, with a mean age of 86 ± 6.5 years. Seventy-six patients (32%) died. Nonsurvivors had a shorter number of days from initial symptoms to hospitalization (P = .007) and the length of stay in acute wards than survivors (P < .001). Similarly, they had a higher prevalence of heart failure (P = .044), peripheral artery disease (P = .009), crackles at clinical status (P < .001), respiratory rate (P = .005), oxygen support needs (P < .001), C-reactive protein (P < .001), bilateral and peripheral infiltrates on chest radiographs (P = .001), and a lower prevalence of headache (P = .009). Furthermore, nonsurvivors were more often frail (P < .001), with worse functional status (P < .001), higher comorbidity burden (P < .001), and delirium at admission (P = .007). A multivariable Cox model showed that male sex (HR 4.00, 95% CI 2.08-7.71, P < .001), increased fraction of inspired oxygen (HR 1.06, 95% CI 1.03-1.09, P < .001), and crackles (HR 2.42, 95% CI 1.15-6.06, P = .019) were the best predictors of mortality, while better functional status was protective (HR 0.98, 95% CI 0.97-0.99, P = .001). CONCLUSIONS AND IMPLICATIONS: In older patients hospitalized for COVID-19, male sex, crackles, a higher fraction of inspired oxygen, and functionality were independent risk factors of mortality. These routine parameters, and not differences in age, should be used to evaluate prognosis in older patients.

[Issues and challenges related to COVID-19 in acute geriatric care: lessons learned from the Geneva experience]. / Enjeux et défis du Covid-19 en gériatrie aiguë: leçons tirées de l'expérience genevoise.

The older patients have been the most affected by the SARS-CoV-2 pandemic. In addition, this infection has been responsible for high mortality rate in this population. In this article we wanted to describe the clinical findings we encountered in older people with COVID-19 and share some of the issues and challenges we faced during the COVID-19 pandemic.

Les personnes âgées ont été les plus touchées par la pandémie de SARS-CoV-2. De plus, cette infection a été responsable d'une mortalité élevée au sein de cette population. Dans cet article, nous avons souhaité décrire les particularités cliniques du Covid-19 que nous avons constatées chez les patients âgés et faire part de plusieurs enjeux et défis auxquels nous avons été confrontés au cours de la pandémie de Covid-19.

Feasibility and safety of high-intensity interval training for the rehabilitation of geriatric inpatients (HIITERGY) a pilot randomized study.

BACKGROUND: High-intensity interval training (HIIT) has been shown to be more effective than moderate-intensity continuous training (MICT) for the physical rehabilitation. However, data on its suitability for older hospitalized patients is scarce. METHODS: Randomized controlled trial in a hospital setting. Inclusion of 100 patients, ≥65 years old, hospitalized for rehabilitation after an acute medical condition, in a two-week rehabilitation program of either four HIIT or three MICT sessions per week. Completion was defined as participation in all but two planned sessions accomplishing ≥50% of each session. We assessed: upper-limb muscle strength (handgrip isometric strength test), lower-limb muscle strength (quadriceps and ankle flexion and extension tests); gait speed and spatio-temporal parameters (instrumented walkway), and exercise capacity (6-min walk test). All adverse events were recorded as safety endpoints. RESULTS: An intention-to-treat analysis showed a 44% completion rate for the HIIT group (95% CI, 30-59) and 77% for MICT (95% CI, 55-82). A modified intention-to-treat analysis restricted to patients who participated in ≥1 session showed an 88% completion rate in the HIIT group (95%CI, 69-97) and an 80% completion rate in MICT (95%CI, 65-90). The exercises most frequently undertaken were the pedal exerciser (54%) and the NuStep (32%). There were no significant differences in the various measures. No serious adverse events occurred. CONCLUSION: A HIIT rehabilitation program for this population was feasible, safe and had a high adherence rate. TRIAL REGISTRATION NUMBER: Clinicatrials.gov ID: NCT02318459.

Prevalence of oral hygiene tools amongst hospitalised elders: A cross-sectional survey.

OBJECTIVE: This study aimed to evaluate the prevalence of various oral hygiene tools amongst hospitalised elders and to associate their cognitive status with the prevalence of tools and oral hygiene status. MATERIALS AND METHOD: Elderly hospitalised participants were included in the study and underwent a brief clinical intra-oral examination. A semi-structured questionnaire evaluated the awareness and personal possession of the various oral hygiene tools. Participants' personal information and various clinical parameters including DMF (T) index, plaque index, CPITN index, denture plaque and calculus index were collected. Mini-Mental State Examination (MMSE) scores were retrieved from the medical records. Linear regression models were applied for statistical analyses (P < 0.05). RESULTS: A total of 100 hospitalised elders (age = 84.5 ± 6.9 years; ♀ = 72, age = 84.9 ± 7.2 years; ♂ = 28, age = 83.3 ± 5.8 years) participated in this study. Awareness was high for manual toothbrush (100%), electric toothbrush (86%), dental floss (79%), interdental brush (44%), interdental stick (55%) and mouthwash (75%), but was low for tongue scraper (9%), while the prevalence of use was 93%, 17%, 27%, 21%, 29%, 39% and 4%, respectively. Linear regression models revealed plaque scores were lower when more hygiene tools were used by the participants (P = 0.0059). Participants with high MMSE scores had lower plaque scores (P = 0.0004) and possessed more oral hygiene tools (P = 0.0203). CONCLUSION: Poor oral hygiene is often noticed in institutionalised elders and might be related to a lack of knowledge about existing oral hygiene tools. These may help optimising oral hygiene, especially in cognitively impaired elders. Oral hygiene tools should be prescribed according to the patient's need, functional and cognitive status.

Reliability and performance of the Swiss Emergency Triage Scale used by paramedics.

OBJECTIVES: No general emergency department triage scale has been evaluated for prehospital triage. The objective of this study was to evaluate the reliability and the performance of the Swiss Emergency Triage Scale (SETS) used by paramedics to determine the emergency level and orientation of simulated patients. PATIENTS AND METHODS: In a prospective cross-sectional study, 23 paramedics evaluated 28 clinical scenarios with the SETS using interactive computerized triage software simulating real-life triage. The primary outcome was inter-rater reliability regarding the triage level among participants measured by intraclass correlation coefficient (ICC). Secondary outcomes were the accuracy of triage level and the reliability and accuracy of orientation of patients of at least 75 years to a dedicated geriatric emergency centre. RESULTS: Twenty-three paramedics completed the evaluation of the 28 scenarios (644 triage decisions). Overall, ICC for triage level was 0.84 (95% confidence interval: 0.77-0.99). Correct emergency level was assigned in 89% of cases, overtriage rate was 4.8%, and undertriage was 6.2%. ICC regarding orientation in the subgroup of simulated patients of at least 75 years was 0.76 (95% confidence interval: 0.61-0.89), with 93% correct orientation. CONCLUSION: Reliability of paramedics rating simulated emergency situations using the SETS was excellent, and the accuracy of their rating was very high. This suggests that in Switzerland, the SETS could be safely used in the prehospital setting by paramedics to determine the level of emergency and guide patients to the most appropriate hospital.

Type I Gaucher disease with bullous pemphigoid and Parkinson disease: A case report.

RATIONALE: Gaucher disease (GD) is a rare genetic lysosomal storage disorder inherited in an autosomal recessive pattern. GD is due to the deficiency of a lysosomal enzyme, acid beta-glucosidase (or glucocerebrosidase). Type 1 Gaucher disease (GD1) is characterized by thrombocytopenia, anemia, an enlarged spleen, and liver as well as bone complications (Erlenmeyer flask deformity, osteoporosis, lytic lesions, pathological and vertebral fractures, bone infarcts, and avascular necrosis leading to degenerative arthropathy). The diagnosis is usually made in first decades but is sometimes delayed. Parkinson disease, neoplasia, and immune system abnormalities may be associated with GD1. PATIENT CONCERNS: A patient known for hepatosplenomegaly with hyperferritinemia, anemia, and thrombocytopenia was admitted for Lewy body dementia and bullous pemphigoid. DIAGNOSES: Type 1 Gaucher disease. INTERVENTION: No specific treatment started. OUTCOMES: patient died ten months later due to pneumonia. LESSONS: To the best of our knowledge, this is the first case of the association between GD1, bullous pemphigoid, and Lewy body dementia. We discuss the central role of alpha-synuclein in these pathologies.

[Right heart failure : important forold and young patientsA challenge from the acute to the chronic]. / Insuffisance ventriculaire droite :chez le sujet âgé mais aussi chez le jeuneUn défi de l'aigu au chronique.

The prevalence of the right heart failure (RHF) is poorly known. However, RHF is often a consequence of left heart failure due to an interdependance between both ventricles. RHF should be indentified because of prognostic relevance. RHF is defined by the inability to maintain adequate cardiac output through the lung circulation. It can result from volume overload, pressure overload, or a disorder of systolic function. Adaptive mechanisms such as dilation or hyper-trophy will maintain adequate hemodynamics. Once these mechanisms become insufficient, congestive signs and hemodynamic consequences will appear. Diagnosis is based on echocardiography. The treatment of RHF is similar to left heart failure. In case of acute RHF, treatment depends of the etiology of RHF. Optimization of the volemia is a central objective of therapeutics.

Sa prévalence est peu connue, l'insuffisance ventriculaire droite (IVD) est souvent associée à l'insuffisance cardiaque gauche (ICG) du fait de l'interdépendance ventriculaire. L'IVD mérite d'être identifiée du fait de son pronostic. Traduisant l'incapacité du VD à assurer un débit cardiaque suffisant à travers la circulation pulmonaire, elle peut résulter d'une surcharge volémique, ou en pression ou un trouble contractile. Des mécanismes d'adaptation tels qu'une dilatation ou une hypertrophie peuvent maintenir une hémodynamique adaptée. En l'absence de réponse des signes cliniques vont apparaître. Le diagnostic repose sur des critères échocardiographiques. Le traitement de l'IVD chronique se rapproche de celui de l'ICG. La prise en charge de l'IVD aiguë dépend de la cause. L'optimisation de la volémie est essentielle dans le traitement.

A Case of Tuberculous Granulomatous Panniculitis without Vasculitis.

We report a case of tuberculous granulomatous panniculitis without vasculitis in an 87-year-old female patient with B-cell chronic lymphocytic leukaemia. One month after starting chemotherapy with chlorambucil and prednisone she presented superficial erythematous plaques on the anterior side of the left leg. Three weeks later erythematous painless deep nodules appeared on the left popliteal fossa and on the left thigh. Cutaneous biopsy revealed granulomatous panniculitis without caseation necrosis or vasculitis. Polymerase chain reaction for Mycobacterium tuberculosis revealed positivity in the skin. The final diagnosis was reactivation of latent tuberculosis (TB) induced by deep immunosuppression associated with chemotherapy and haematological disease. Tuberculous granulomatous panniculitis without vasculitis is a rare presentation of cutaneous TB and may be part of the heterogeneous histopathologic spectrum of erythema induratum of Bazin (nodular vasculitis). Our case shows that the diagnosis of cutaneous TB requires the correlation of clinical findings with histopathology and microbiological tests.
