Background: Geriatric conditions (GCs) are common in the elderly population, but their clinical significance in acute care is not well understood. In this study, we first investigated the cross-sectional associations of GCs with frailty and polypharmacy at the time of admission to an acute care geriatric ward. Then, to clarify the clinical significance of GCs in acute care, we prospectively examined the association of GCs with the incidence of hospital-acquired complications and consequences after discharge.Methods: Participants were 184 patients (40.2% male: mean age, 85.0 ± 6.0 years) hospitalized in an acute care geriatric ward at a university hospital. We examined the cross-sectional associations of GCs with frailty and polypharmacy by multiple regression analysis, and then the associations of GCs with the incidence of hospital-acquired complications, falls, and death within 3 months of discharge by multiple logistic regression analysis.Results: GCs were associated with frailty and use of polypharmacy, independent of multiple morbidity. GCs were also associated with re-admission within 3 months of discharge; however, there was no significant association with the incidence of hospital-acquired complications, falls, or mortality after discharge.Conclusions: These findings suggest that GCs are clinically significant in the hospitalized elderly and further research on GCs is warranted.

Technological advances of hand-held ultrasound devices and educational programmes for their use, such as point-of-care ultrasonography (POCUS) training, have contributed to the increasing application of these devices in clinical practice. With the greater impact of frailty and sarcopenia in aging societies, attention is being focused on the use of ultrasound for skeletal muscle assessment. In this narrative review, we discuss how ultrasound can be applied to skeletal muscle assessment, especially that of the quadriceps muscle, in clinical practice. Muscle thickness by ultrasound has been shown to have good reliability and validity for the evaluation of muscle size, and echo intensity has been used to evaluate muscle quality. Muscle ultrasound has not only been useful to diagnose sarcopenia in various settings, but has also been validated to predict health-related outcomes such as death and functional disability. Recommended methods for muscle ultrasound was published recently, and the results of future studies are expected to be comparable. Although several challenging issues with muscle ultrasound remain, if it could be incorporated into educational programmes such as POCUS training, more clinicians may be able to use ultrasound for skeletal muscle assessment in the future.KEY MESSAGESThe evolution of hand-held ultrasound devices enables physicians to perform ultrasound at the bedside as part of regular medical examinations.Muscle ultrasound is considered an effective tool for evaluating muscle size and quality, and has been studied in various settings.More clinicians may be able to evaluate skeletal muscle assessment with the development of educational programmes on muscle ultrasound in the future.

IgG4-related disease (IgG4-RD) which is characterized by an autoimmune abnormality and elevated serum IgG4 level often presents as swelling, nodules, and the thickening of multiple organs. It typically occurs in middle-aged to elderly patients, but its pathogenesis remains unclear. Lymphadenopathy is frequently seen in IgG4-RD, which clinically requires a differential diagnosis from malignant lymphoma. We herein report a case of malignant lymphoma with IgG4-RD arising in a very elderly man.An 85-year old man with a 6-year history of autoimmune pancreatitis was diagnosed as IgG4-related hypophysitis 13 months prior to admission. Hydrocortisone was prescribed for secondary adrenal insufficiency after this presentation. At 9 months before admission, he began to suffer from central diabetes insipidus, and desmopressin was also prescribed at that time. However, 9 months later, he presented with fever, weight loss, and systemic lymphadenopathy while demonstrating elastic hardness, flexibility, and no tenderness. A pathologic specimen obtained from a right axillary lymph node biopsy revealed diffuse large B cell lymphoma. Considering his age and performance status, palliative therapy was chosen, and thus prednisolone was administered. He was transferred to another hospital to receive palliative care on the 55th day after hospitalization.We should consider the clinical course, pathological findings, serum IgG4 level, and other involved organs in order to differentiate malignant lymphoma from IgG4-related lymphadenopathy. To our knowledge, this case is the oldest known patient to have ever been reported. Both IgG4-RD and malignant lymphoma are frequently seen in elderly people, therefore, we should deepen our knowledge of these diseases.

Individuals with mild cognitive impairment (MCI) often make qualitative errors on the Clock Drawing Test (CDT), and these errors are reported to be associated with lower scores on neuropsychological assessments. Gait speed is also closely associated with cognitive dysfunction. However, the association between CDT errors and gait speed has not been investigated in individuals with MCI. Therefore, in this study, we explored the association between gait speed and qualitative errors on the CDT. Participants were 196 outpatients at a memory clinic with a clinical dementia rating of 0.5. The CDT was evaluated using the method of Cahn et al. The participants were divided into tertiles of normal and maximum gait speeds. The CDT error types of stimulus-bound response, conceptual deficit (CD), and planning deficit were found in 24.5%, 29.6%, and 30.1% of the participants, respectively. CD was found in 43.6% of the slowest tertile of maximum gait and in 22.2% of the fastest tertile. Multiple linear regression analysis gait speeds as objective continuous variables revealed that CD was significantly negatively associated with maximum gait, but not with normal gait. No other error types were associated with gait speeds. Only CD type error on the CDT was negatively associated with maximum gait speed, but not normal gait speed in the current study. The association between the qualitative error on the CDT and gait speed provides further basis of the clinical importance of qualitative assessments of CDT.

Chronic dehydration mainly occurs due to insufficient fluid intake over a lengthy period of time, and nursing home residents are thought to be at high risk for chronic dehydration. However, few studies have investigated chronic dehydration, and new diagnostic methods are needed. Therefore, in this study, we aimed to identify risk factors for chronic dehydration by measuring serum osmolality in nursing home residents and also to evaluate whether examining the inferior vena cava (IVC) and determining the IVC collapsibility index (IVC-CI) by ultrasound can be helpful in the diagnosis of chronic dehydration. A total of 108 Japanese nursing home residents aged &ge, 65 years were recruited. IVC measurement was performed using a portable handheld ultrasound device. Fifteen residents (16.9%) were classified as having chronic dehydration (serum osmolality &ge, 295 mOsm/kg). Multivariate logistic regression analysis showed that chronic dehydration was associated with dementia (odds ratio (OR), 6.290, 95% confidential interval (CI), 1.270&ndash, 31.154) and higher BMI (OR, 1.471, 95% CI, 1.105&ndash, 1.958) but not with IVC or IVC-CI. Cognitive function and body weight of residents should be considered when establishing a strategy for preventing chronic dehydration in nursing homes.

To evaluate the predictability of progression of cognitive impairment to dementia using qualitative clock drawing test (CDT) scores, we administered both the CDT using Cahn et al.’s qualitative scoring system and the Mini-Mental State Examination (MMSE) to assess cognitive function in non-demented older individuals attending a memory clinic at a university hospital. Patients visiting the clinic for assessment of cognitive function between January 2015 and December 2019 were enrolled, and only those who were diagnosed as not having dementia at the time of initial assessment completed a follow-up assessment at 1 y (n = 163). To examine any association of qualitative CDT score with progression to dementia, multiple logistic regression analysis was conducted with the change in diagnosis from non-dementia to dementia at 1 y as the dependent variable. A total of 26 participants (16.0%) were diagnosed as having converted to dementia. Multiple logistic regression analysis revealed that both the qualitative CDT score using Cahn et al.’s scoring system and the existence of conceptual deficits were significantly associated with progression to dementia at 1 y after initial assessment of cognitive function, irrespective of the MMSE score, among non-demented older individuals. The CDT may be a useful predictor of progression to dementia in primary care settings.

Introduction Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease that was first reported in China in 2011. However, it is now endemic in Japan, and the SFTS viruses in Japan and China have evolved independently. Its fatality rate is 26.5 % in Japan, and the viral load is related to morbidity. Case description We encountered two patients with SFTS. Case 1 is a 72-year-old woman who visited our hospital owing to severe fatigue, diarrhea, and nausea. Her consciousness level score on the Glasgow Coma Scale was 14 points, and her serum lactate dehydrogenase level was 646 IU/L. Case 2 is an 82-year-old woman who visited our hospital owing to diarrhea and general fatigue. Her consciousness level score on the Glasgow Coma Scale was 11 points, and her serum lactate dehydrogenase level was 935 IU/L. Discussion and evaluation Both patients had hemophagocytic syndrome and presented with similar symptoms. Although both were treated with similar drug regimens, their clinical courses were different: after treatment, the 72-year-old woman survived whereas the 82-year-old woman died. In addition to age, the two patients differed in terms of time between symptom onset and treatment initiation, consciousness level, viral load, and extent of elevation of liver enzyme levels. Conclusions The viral load, which is a predictor of morbidity, was associated with the level of consciousness and the serum lactate dehydrogenase level, both of which might be useful for predicting death in patients with SFTS.
