RESUMO
The research was conducted to investigate the improvement of agitated behaviors, cognitive functions, and negative emotions among patients with senile dementia and the burden of caregivers after simulated presence therapy (SPT) intervention. 85 Patients with senile dementia were included as the research subjects and divided into control group (40 cases performed with routine nursing) and observation group (45 cases undergoing routine nursing combined with SPT) via a random number table method. Cohen-Mansfield agitation inventory (CAMI) and protective constraint were used to assess the improvement of agitated behaviors among patients. Besides, apathy evaluation scale-informant (AES-I), functional independence measure (FIM), self-rating depression scale (SDS), self-rating anxiety scale (SAS), clock drawing test, and caregiver burden inventory (CBI) were adopted to evaluate the differences in apathy, daily living and sociability, depression, anxiety, cognitive functions, and caregiver burden between the two groups. It was demonstrated that CAMI score, the duration of protective constraint use, AES-I score, SDS score, SAS score, and CBI score among patients in observation group all apparently decreased compared with those in control group after the intervention. In contrast, FIM and clock drawing test scores both notably increased (p < 0.05). The above findings suggested that SPT could obviously reduce the incidence of agitated behaviors, improve the level of apathy, daily living and sociability, depression, anxiety, and cognitive functions, and relieve caregiver burden among patients with senile dementia during SPT intervention for patients with senile dementia.
RESUMO
In the treatment of coronavirus infections, it is important not only to understand the course of the disease, but also to understand what is happening in the human body, especially in the circulatory system, that is, which disorders lead to deterioration and further complications. Hemostasis disorder in COVID-19 plays an important role in the etiology and clinical manifestations of the disease. The ability to identify factors and risk groups for the development of thrombotic complications, the ability to dynamically interpret peripheral blood parameters and coagulograms, knowledge of diagnostic criteria for possible hemostasis disorders (for example, DIC syndrome, sepsis-associated coagulopathy, antiphospholipids, hemophagocytosis and hypercoagulation syndrome) are necessary to determine the indications for the test. Differentiated prescribing of clinically justified therapy (including anticoagulants and blood components) is important, which determines the complexity of treatment and prognosis for patients with COVID-19. This article is a review of the literature on the topic of hemostasis disorders in elderly and senile patients with mesenteric thrombosis in COVID 19 over the past few years.

This study aimed to assess PEMF in a rat model of senile osteoporosis and its relationship with NLRP3-mediated low-grade inflammation in the bone marrow microenvironment. A total of 24 Sprague Dawley (SD) rats were included in this study. Sixteen of them were 24-month natural-aged male SD rats, which were randomly distributed into the Aged group and the PEMF group (n = 8 per group). The remaining 8 3-month -old rats were used as the Young positive control group (n = 8). Rats in the PEMF group received 12 weeks of PEMF with 40 min/day, five days per week, while the other rats received placebo PEMF intervention. Bone mineral density/microarchitecture, serum levels of CTX-1 and P1CP, and NLRP3-related signaling genes and proteins in rat bone marrow were then analyzed. The 12-week of PEMF showed significant mitigation of aging-induced bone loss and bone microarchitecture deterioration, i.e. PEMF increased the bone mineral density of the proximal femur and L5 vertebral body and improved parameters of the proximal tibia and L4 vertebral body. Further analysis showed that PEMF reversed aging-induced bone turnover, specifically, decreased serum CTX-1 and elevated serum P1CP. Furthermore, PEMF also dramatically inhibited NLRP3-mediated low-grade inflammation in the bone marrow, i.e. PEMF inhibited the levels of NLRP3, proCaspase1, cleaved Caspase1, IL-1ß, and GSDMD-N. The study demonstrated that PEMF could mitigate the aging-induced bone loss and reverses the deterioration of bone microarchitecture probably through inhibiting NLRP3-mediated low-grade chronic inflammation to improve the inflammatory bone microenvironment in aged rats.

CONTEXT: Qinggong Shoutao Wan (QGSTW) is a pill used as a traditional medicine to treat age-associated memory decline (AAMI). However, its potential mechanisms are unclear. OBJECTIVE: This study elucidates the possible mechanisms of QGSTW in treating AAMI. MATERIALS AND METHODS: Network pharmacology and molecular docking approaches were utilized to identify the potential pathway by which QGSTW alleviates AAMI. C57BL/6J mice were divided randomly into control, model, and QGSTW groups. A mouse model of AAMI was established by d-galactose, and the pathways that QGSTW acts on to ameliorate AAMI were determined by ELISA, immunofluorescence staining and Western blotting after treatment with d-gal (100 mg/kg) and QGSTW (20 mL/kg) for 12 weeks. RESULTS: Network pharmacology demonstrated that the targets of the active components were significantly enriched in the cAMP signaling pathway. AKT1, FOS, GRIN2B, and GRIN1 were the core target proteins. QGSTW treatment increased the discrimination index from -16.92 ± 7.06 to 23.88 ± 15.94% in the novel location test and from -19.54 ± 5.71 to 17.55 ± 6.73% in the novel object recognition test. ELISA showed that QGSTW could increase the levels of cAMP. Western blot analysis revealed that QGSTW could upregulate the expression of PKA, CREB, c-Fos, GluN1, GluA1, CaMKII-α, and SYN. Immunostaining revealed that the expression of SYN was decreased in the CA1 and DG. DISCUSSION AND CONCLUSIONS: This study not only provides new insights into the mechanism of QGSTW in the treatment of AAMI but also provides important information and new research ideas for the discovery of traditional Chinese medicine compounds that can treat AAMI.

Objective: To evaluate the effects of comprehensive exercise training on frailty, negative emotions and physical functions of elderly patients with diabetes. Methods: This is a retrospective study. A total of 140 elderly patients with T2DM in The No.2 Hospital of Baoding were selected from December, 2021 to June, 2023 and randomly divided into two groups, with 70 patients in each group. The control group was given routine nursing and routine exercise education, and the study group was additionally given comprehensive exercise training. Tilburg frailty indicator (TFI), emotional status, physical functions, grip strength, fasting blood glucose and patient satisfaction were compared and analyzed between the two groups. Results: Before the intervention, TFI showed no significant differences between the two groups (p>0.05). After the intervention, physical, psychological and social frailty in the study group were significantly lower than those in the control group, with statistically significant differences (p= 0.00). SAS and SDS scores reduced significantly in the study group compared with those in the control group after the intervention, with statistically significant differences (p=0.00). After the intervention, the grip strength was significantly larger while the fasting blood glucose was significantly lower in the study group compared with those in the control group, with statistically significant differences (p=0.00). Patient satisfaction in the study group was higher than in the control group, with a statistically significant difference(p=0.03). Conclusion: Comprehensive exercise training for elderly patients with diabetes is beneficial to improving their frail state, negative emotions, blood glucose levels and physical functions. It has significant clinical application value.
RESUMO
Aging is the main risk factor for the appearance of age-related neurodegenerative diseases, including Alzheimer's disease (AD). AD is the most common form of dementia, characterized by the presence of senile plaques (SPs) and neurofibrillary tangles (NFTs), the main histopathological hallmarks in AD brains. The core of these deposits are predominantly amyloid fibrils in SPs and hyperphosphorylated Tau protein in NFTs, but other molecular components can be found associated with these pathological lesions. Herein, an extensive literature review was carried out to obtain the SPs and NFTs proteomes, followed by a bioinformatic analysis and further putative biomarker validation. For SPs, 857 proteins were recovered, and, for NFTs, 627 proteins of which 375 occur in both groups and represent the common proteome. Gene Ontology (GO) enrichment analysis permitted the identification of biological processes and the molecular functions most associated with these lesions. Analysis of the SPs and NFTs common proteins unraveled pathways and molecular targets linking both histopathological events. Further, validation of a putative phosphotarget arising from the in silico analysis was performed in serum-derived extracellular vesicles from AD patients. This bioinformatic approach contributed to the identification of putative molecular targets, valuable for AD diagnostic or therapeutic intervention.

Extracellular aggregates of wild-type human transthyretin are associated with heart diseases such as wild-type transthyretin (TTR)-derived amyloidosis (ATTR-wt). Due to their strategic location, cardiac fibroblasts act as sentinel cells that sense injury and activate the inflammasome. No studies of the effects of TTR amyloid aggregation on the secretion of inflammatory factors by primary human cardiac fibroblasts (hCFs) have been reported yet. The intracellular internalization of TTR aggregates, which correspond to the early stage of ATTR-wt, were determined using immunofluorescence and Western blotting of cell lysates. A further objective of this study was to analyze the secretion of inflammatory factors by hCFs after analysis of TTR amyloid aggregation using X-MAP® Luminex Assay techniques. We show that TTR aggregates are internalized in hCFs and induce the secretion of both Brain Natriuretic Peptide (BNP) and N-terminal pro B-type Natriuretic Peptide(NT-proBNP). Also, pro-inflammatory mediators such as interleukin-6 (IL-6) and IL-8 are secreted without significant changes in the levels of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs). In conclusion, these findings suggest that IL-6 and IL-8 play important roles in the development of ATTR-wt, and indicate that IL-6 in particular could be a potentially important therapeutic target in patients with ATTR-wt.

Alzheimer's disease (AD) is a chronic neurodegenerative disease, with the characteristics of neurofibrillary tangle (NFT) and senile plaque (SP) formation. Although great progresses have been made in clinical trials based on relevant hypotheses, these studies are also accompanied by the emergence of toxic and side effects, and it is an urgent task to explore the underlying mechanisms for the benefits to prevent and treat AD. Herein, based on animal experiments and a few clinical trials, neuroinflammation in AD is characterized by long-term activation of pro-inflammatory microglia and the NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3) inflammasomes. Damaged signals from the periphery and within the brain continuously activate microglia, thus resulting in a constant source of inflammatory responses. The long-term chronic inflammatory response also exacerbates endoplasmic reticulum oxidative stress in microglia, which triggers microglia-dependent immune responses, ultimately leading to the occurrence and deterioration of AD. In this review, we systematically summarized and sorted out that exercise ameliorates AD by directly and indirectly regulating immune response of the central nervous system and promoting hippocampal neurogenesis to provide a new direction for exploring the neuroinflammation activity in AD.

INTRODUCTION: The aim of this study was to investigate the relationship between the high mobility group box-2 (HMGB2) and valve calcification in senile degenerative heart valve disease (SDHVD). METHODS: According to the echocardiographic results, patients with calcified heart valves were used as the experimental group and patients without calcified heart valves were used as the control group; blood was drawn for testing, and serum levels of HMGB2 were measured by an enzyme-linked immunosorbent assay. Human heart valve interstitial cells (hVICs) cultured in vitro were randomly divided into two groups. The calcification group was cultured with a medium containing calcification induction solution and cells were induced on days 1, 3, and 5, and the control group was cultured with a standard medium. Expression of bone morphogenetic protein 4 (BMP-4) and HMGB2 in both groups was detected by Western blot. RT-PCR was performed to detect the expression of the HMGB2 gene during calcification. The hVICs were cultured in vitro for 4 days with different concentrations of exogenous HMGB2 (0.01 µg/mL, 0.1 µg/mL, 1 µg/mL, 2 µg/mL), while the control group was cultured with a standard medium and the expression of BMP-4 and NF-κB P65 was detected by Western blot. RESULTS: The serum level of HMGB2 was 7.90 (5.92, 12.39) µg/L, higher than that of 7.06 (5.06, 9.73) µg/L in the valve calcification group in elderly patients with degenerative valve disease (p = 0.005); the differences were statistically significant. In in vitro experiments, the cellular calcification protein BMP-4 and the HMGB2 protein were higher in the calcification group compared to the control group (p < 0.05). Exogenous stimulation of hVICs with HMGB2 was able to upregulate the expression of BMP-4 and NF-κB P65 (p < 0.05). CONCLUSIONS: HMGB2 is correlated with valvular calcification in senile degenerative heart valve disease. The HMGB2 protein may promote the process of SDHVD valve calcification by activating the NF-κB pathway and upregulating the expression of BMP-4.

Objectives: Alzheimer's disease (AD) is a serious neurodegenerative disease. Although many therapeutic strategies have been studied, their clinical applications are immature. Moreover, these methods can only alleviate symptoms rather than cure it, posing a challenge to brain health in older adults worldwide. Curcumin (CUR) is a very promising natural compound for nerve protection and treatment. It can prevent and treat AD, and on the other hand, its fluorescence properties can be used in the diagnosis of AD. However, CUR is characterized by very low water solubility, fluid instability, rapid metabolism, low bioavailability and difficulty in penetrating the biological barriers, which limit its application. Nanocarriers are a potential material to improve the biocompatibility of CUR and its ability to cross biological barriers. Therefore, delivering CUR by nanocarriers is an effective method to achieve better efficacy. Methods: In this review, the preventive, therapeutic and diagnostic effects of CUR nanoformulations on AD, as well as various patents, clinical trials and experimental research progress in this field are discussed. The aim is to provide detailed reference and practical suggestions for future research. Results: CUR has a variety of pharmacological activities in the prevention and treatment of AD, and its nanoformulation can effectively improve solubility, bioavailability and the ability to penetrate the blood-brain barrier. Significant benefits have been observed in the current study. Discussion: CUR formulations have a good prospect in the prevention, diagnosis and treatment of AD, but the safety and principle of its administration need more detailed study in the future.

As societal aging intensifies, senile osteoporosis has become a global public health concern. Bone microdamage is mainly caused by processes such as enhancing osteoclast activity or reducing bone formation by osteoblast-lineage cells. Compared with young individuals, extracellular vesicles derived from senescent bone marrow mesenchymal stem cells(BMSCs) increase the transient differentiation of bone marrow monocytes (BMMs) to osteoclasts, ultimately leading to osteoporosis and metal implant failure. To address this daunting problem, an exosome-targeted orthopedic implant composed of a nutrient coating was developed. A high-zinc atmosphere used as a local microenvironmental cue not only could inhibit the bone resorption by inhibiting osteoclasts but also could induce the reprogramming of senile osteogenesis and osteoclast dialogue by exosome modification. Bidirectional regulation of intercellular communication via cargoes, including microRNAs carried by exosomes, was detected. Loss- and gain-of-function experiments demonstrated that the key regulator miR-146b-5p regulates the protein kinase B/mammalian target of rapamycin pathway by targeting the catalytic subunit gene of PI3K-PIK3CB. In vivo evaluation using a naturally-aged osteoporotic rat femoral defect model further confirmed that a nutrient coating substantially augments cancellous bone remodeling and osseointegration by regulating local BMMs differentiation. Altogether, this study not only reveals the close link between senescent stem cell communication and age-related osteoporosis but also provides a novel orthopedic implant for elderly patients with exosome modulation capability.

BACKGROUND: Some studies suggested obesity may be beneficial in preventing bone loss through the negative relationship between body mass index (BMI) and osteoporosis in senile. However, using BMI to measure obesity is unconvincing due to confounding factors such as muscle mass were not taken into account, and few articles have yet taken a better way to evaluate the relationship between obesity and osteoporosis. METHODOLOGY: Using a cross-sectional sample of 1,979 participants aged ≥65 years from the National Health and Nutrition Examination Survey (NHANES) 2017 to 2020, we evaluated the relation of weight-adjusted waist index (WWI) with osteoporosis. WWI was calculated as waist (cm) divided by the square root of body weight (kg). Diagnosis of osteoporosis was described as follows: according to the updated reference for calculating bone mineral density T-Scores, we marked the BMD value as X, using the formula T femoral neck= (X g/cm2-0.888 g/cm2)/0.121 g/cm2, T lumbar spine= (X g/cm2- 1.065 g/cm2)/0.122 g/cm2, and defined those with a final T femoral neck <-0.25. T lumbar spine<-0.25 or patients with previously diagnosed OP in other hospitals as osteoporosis. RESULTS: All the 1,979 participants were between 65 and 80 years, there were 379 (21.1%) with osteoporosis, 608 (30.7%) with WWI exceeding 12 (cm/âkg) (range 8.85-14.14), and 955 (48.3%) women. Furthermore, the relationship between WWI and osteoporosis was nonlinear with a threshold effect point. Odds of OP significantly increased with the increase of WWI (OR 2.33, 95% CI 11.48-3.38, Pâ¯=â¯0.0001) at the right side of the threshold point (WWI≥12) according to the threshold effect study. CONCLUSIONS: Found a significant positive relationship between WWI and osteoporosis. Body fat management in the senile may be good to prevent osteoporosis if confirmed by other prospective studies analyzing the longitudinal risk of osteoporosis with obesity.

INTRODUCTION: Senile osteoporosis is one of the most common age-related diseases worldwide. Glucagon like peptide-2 (GLP-2), a naturally occurring gastrointestinal peptide, possesses therapeutic effects on bone loss in postmenopausal women and ovariectomized rats. However, the role of GLP-2 in senile osteoporosis and underlying mechanisms has not been explored. METHODS: GLP-2 was subcutaneously injected into the 6-month-old male senile osteoporosis model of senescence-accelerated mouse prone 6 (SAMP6) mice for 6 weeks. SAMP6 subjected to normal saline and senescence-accelerated mouse resistant 1 served as control groups. Micro-computed tomography was performed to evaluate the bone mass and microarchitecture of the mice. Osteoblastic and osteoclastic activities were determined by biochemical, quantitative real-time PCR, histological, and histomorphometric analyses combined with hematoxylin-eosin, toluidine blue, and tartrate-resistant acid phosphatase staining. We also examined the proteins and structure of intestinal tight junction using immunohistochemical assay as well as a transmission electron microscope. Serum inflammation marker levels were measured using ELISA. Additionally, anti-oxidative enzymes GPX-4 and SOD-2 and receptors of GLP-2 and vitamin D expression in the ileum and colon were detected under immunofluorescence staining. RESULTS: Six-week GLP-2 treatment attenuated bone loss in SAMP6 mice, as evidenced by increased bone mineral density, improved microarchitecture in femora, and enhanced osteogenic activities. In contrast, the activity of osteoclastic activity was not obviously inhibited. Moreover, GLP-2 ameliorated tight junction structure and protein expression in the intestinal barrier, which was accompanied by the reduction of TNF-α level. The expression of receptors of intestinal GLP-2 and vitamin D in the ileum was elevated. Furthermore, the oxidative stress in the intestines was improved by increasing the GPX-4 and SOD-2 signaling. CONCLUSION: Our findings suggest that GLP-2 could ameliorate age-associated bone loss, tight junction structure, and improved antioxidant enzyme activity in the gut in SAMP6 mice. Amelioration of gut barrier dysfunction may potentially contribute to improving bone formation and provide evidence for targeting the entero-bone axis in the treatment of senile osteoporosis.

Progressive articular surface degradation during arthritis causes ongoing pain and hyperalgesia that lead to the development of functional disability. TRPA1 channel significantly contributes to the activation of sensory neurons that initiate neurogenic inflammation and mediates pain signal transduction to the central nervous system. Peptide Ms 9a-1 from the sea anemone Metridium senile is a positive allosteric modulator of TRPA1 and shows significant anti-inflammatory and analgesic activity in different models of pain. We used a model of monosodium iodoacetate (MIA)-induced osteoarthritis to evaluate the anti-inflammatory properties of Ms 9a-1 in comparison with APHC3 (a polypeptide modulator of TRPV1 channel) and non-steroidal anti-inflammatory drugs (NSAIDs) such as meloxicam and ibuprofen. Administration of Ms 9a-1 (0.1 mg/kg, subcutaneously) significantly reversed joint swelling, disability, thermal and mechanical hypersensitivity, and grip strength impairment. The effect of Ms 9a-1 was equal to or better than that of reference drugs. Post-treatment histological analysis revealed that long-term administration of Ms9a-1 could reduce inflammatory changes in joints and prevent the progression of cartilage and bone destruction at the same level as meloxicam. Peptide Ms 9a-1 showed significant analgesic and anti-inflammatory effects in the model of MIA-induced OA, and therefore positive allosteric modulators could be considered for the alleviation of OA symptoms.

BACKGROUND: The aging of the population is a social problem faced by many countries in the world. With the increase in the elderly population, the number of patients with Kummell's disease is also gradually increasing. No study has demonstrated that Kummell's disease has a clear correlation with the foramen of a vertebrobasilar vein. OBJECTIVES: The research was conducted to describe and evaluate the morphological characteristics of a basivertebral foramen in patients with osteoporosis and Kummell's disease by CT; to infer whether the specific morphological characteristics of basivertebral foramen may be one of the risk factors of Kummell's disease; to provide clinical suggestions for the treatment of Kummell's disease. DESIGN: Retrospective analysis from January 2020 to December 2021 on 83 patients with 83 vertebral bodies (T8-L5) diagnosed with senile osteoporosis and Kummell's disease hospitalized in our hospital due to chronic low back pain, including 57 women and 23 men. Group A was assigned for the following patients: the age ranged from 59 to 86 years old, with the average age of 67.30 ± 7.32 years old; the body mass index ranged from 20.01 to 29.46 kg/m2, with the average body mass index of 23.51 ± 3.03 kg/m2.Group B was assigned for the following patients: 83 patients diagnosed with senile osteoporosis in our outpatient department from January 2020 to December 2021, including 41 males and 42 females; the age ranged from 60 to 85 years, with an average age of 68.52 ± 4.68 years old; the height to weight ratio met the normal reference standard (except 20% above or 10% below the standard weight). Through the lanwon PACS imaging system, the related parameters of the vertebrobasilar foramen in patients with osteoporosis and Kummell's disease were measured to evaluate and analyze the correlation between the morphological characteristics of the vertebrobasilar foramen in patients with osteoporosis and Kummell's disease. RESULTS: In patients with osteoporosis, the distribution of incidence rate of Kummell's disease in the spine was consistent with that of osteoporotic compression fractures. Sagittal view of the vertebral body on CT scan and the triangular-shaped, trapezoidal-shaped, and irregular-shaped basivertebral foramen in group A accounted for 18%,57%,and 36%,respectively. In group B, triangular-shaped, trapezoidal-shaped, and irregular-shaped foramen accounted for 51%,17%,and 26%,respectively.The distribution of triangular-shaped, trapezoidal-shaped, and irregular-shaped foramen was compared between groups A and B, and the difference was recorded as statistically significant (P < 0.05). Additionally, the difference in the distribution of triangular-shaped, trapezoidal-shaped, and irregular-shaped foramen in group A was found statistically significant (P < 0.05),while that of Group B was found statistically insignificant (P > 0.05).On a horizontal CT scan of the vertebra of group A, triangles, trapezoids, and irregularities accounted for 28%, 26%, and 47%, respectively. In group B, triangles,trapezoids,and irregularities accounted for 31%, 37%, and 30%, respectively. The difference in the distribution of the triangular-shaped and trapezoidal-shaped foramen in groups A and B was statistically insignificant (P > 0.05), while that of irregular-shaped was statistically significant (P < 0.05). Additionally, there was no statistical significance (P > 0.05) in the difference in the morphological distribution of triangular-shaped and trapezoidal-shaped foramen in group A, while that of irregular-shaped was found to be statistically significant (P < 0.05). Further, the difference in the morphological distribution of triangular-shaped, trapezoidal-shaped, and irregular-shaped foramen in group B was not statistically significant (P > 0.05).In general, about 8% of the vertebral body of BF has an osseous septum. In group A, 97% are single-holed while the remaining 3% are porous; in group B, those with single holes accounted for 76%, while the remaining 24% are porous. In groups A and B, the difference in the morphological distribution of single-holed and multi-holed T8, T11, T12, L1, L2, L4, and L5 vertebral bodies was statistically significant (P < 0.05). In group A, the difference in the distribution of single-holed and multi-holed L1 and L5 vertebral bodies was statistically significant (P < 0.05). Similarly, the difference in the distribution of single-holed and multi-holed T8, T11, T12, L1, L2, and L4 basivertebral foramen was statistically significant (P < 0.05). CONCLUSIONS: In patients with osteoporosis, the incidence of vertebral Kummell's disease can be associated with the morphological characteristics of the basivertebral foramen, as observed in the CT scan. Furthermore, the vertebral body with trapezoidal-shaped and irregular-shaped basivertebral foramen and boneless septum in the foramen is highly susceptible to Kummell's disease.

BACKGROUND/PURPOSE: Osteoporotic fracture introduce enormous societal and economic burden, especially for long-term care residents (LTCRs). Although osteoporosis prevention for LTCRs is urgently needed, obstacles such as frail status and inconvenient hospital visits hurdled them from necessary examinations and diagnoses. We aimed to test 10 existing osteoporosis screening tools (OSTs), which can be easily used in institutions and serve as a prediction, for accurately determining the outcome of a Taiwan's National Health Insurance (NHI)-reimbursed anti-osteoporosis medications (AOMs) application for LTCRs. METHODS: This prospective analysis recruited 444 patients from LTC institutions between October 2018 and November 2019. Predictions of whether the NHI-reimbursed AOMs criteria was met were tested for 10 OSTs. The results of OSTs categorized into self-reported or validated based on previous fracture history were self-reported by LTCRs or validated by imaging data and medical records, respectively. The receiver operating characteristic curve and the optimal cut-off points for LTCRs based on Youden's index were explored. RESULTS: Overall, the validated OSTs had a higher positive predictive value (PPV) and negative predictive value (NPV) summation than the corresponding reported OSTs. The validated FRAX-Major was the best OST (PPV = 63.6%, NPV = 82.4% for the male group and, PPV = 78.8%, NPV = 90.0% for the female group). After applying the optimum cut-off derived from Youden's index, the validated FRAX-Major (PPV = 75.4%, NPV = 92.0%)) remained performed best for men. In female population, validated FRAX-Major (PPV = 87.2%, NPV = 84.1%) and validated osteoporosis prescreening risk assessment (OPERA; PPV = 96.1%, NPV = 79.7%)) both provided good prediction results. CONCLUSION: FRAX-Major and OPERA have better prediction ability for LTCRs to acquire NHI-reimbursed AOMs. The validated fracture history and adjusted cut-off points could prominently increase the PPV during prediction.

In June 2021, the world was informed about a new drug for Alzheimer's disease approved by the FDA. Aducanumab (BIIB037, ADU), being a monoclonal antibody IgG1, is the newest AD treatment. The activity of the drug is targeted towards amyloid ß, which is considered one of the main causes of Alzheimer's disease. Clinical trials have revealed time- and dose-dependent activity towards Aß reduction, as well as cognition improvement. Biogen, the company responsible for conducting research and introducing the drug to the market, presents the drug as a solution to cognitive impairment, but its limitations, costs, and side effects are controversial. The framework of the paper focuses on the mechanism of aducanumab's action along with the positive and negative sides of the therapy. The review presents the basis of the amyloid hypothesis that is the cornerstone of therapy, as well as the latest information about aducanumab, its mechanism of action, and the possibility of the use of the drug.

An important area of medical and social research is prospective studies of a cohort of older patients with chronic non-communicable diseases aimed at studying the level of mortality, taking into account the presence/absence of senile asthenia syndrome. A prospective clinical and epidemiological study was conducted on 1 261 people aged 80 years and older receiving medical care on an outpatient basis. Three groups of patients were formed: without senile asthenia syndrome (7,6%), in a state of pre-asthenia (23,5%), with senile asthenia (68,9%). After a calendar year, an analysis was made of the causes of death of respondents in all three groups. A high statistically significant incidence of chronic diseases in patients with senile asthenia syndrome compared with those without signs of this syndrome was noted in arterial hypertension, chronic heart failure, osteoarthritis, age-related macular degeneration, chronic kidney disease, dementia, cancer, anemia, uncomplicated diabetes mellitus. In the structure of causes of death in patients aged 80 years and older, diseases of the circulatory system, nervous system, neoplasms, liver diseases, and diabetes mellitus predominated. The odds ratio of the risk of dying within a year in patients without frailty syndrome is 0,32 (compared to patients with frailty, in which the risk is taken as 1).

The review article analyzes scientific publications devoted to the actual problem of modern society - the syndrome of falls in elderly and senile people. The multifactorial nature of falls is demonstrated, which must be taken into account when carrying out diagnostic and therapeutic measures. The information obtained made it possible to identify the most significant conditions and diseases leading to an increase in the frequency of falls. The paper systematizes information about the causes of falls and the prevention of falls, diagnosis and complex treatment of elderly and senile patients. Attention is drawn to the victims of elderly and senile age with traumatic injuries.

The search for literature sources in domestic and foreign databases showed the absence of works devoted to the study of risk factors for venous thromboembolic events (VTE) in patients of the older age group with diabetes mellitus who are planned to undergo surgical interventions on the spine, which was the impetus for this study. The aim of the study was to study the risk factors for VTE in elderly and senile patients with diabetes mellitus who are scheduled for spinal surgery. A single-center retrospective study included 119 elderly and senile patients (64 men, 55 women, mean age 74,2±6,5 years) who underwent various surgical interventions on the spinal column. According to the binary logistic regression model, the following parameters are statistically significantly associated with the development of VTEC in the studied group of respondents: age of patients over 75 years (p=0,048), HbA1C levels over 7,5% (p=0,007) and D-dimer over 0,5 mg /l FEU (p=0,034), as well as high risk (5 points or more) of VTE according to Caprini scale (p=0,012). In order to reduce the incidence of VTE in elderly and senile patients with diabetes mellitus who are planned to perform surgical interventions on the spine, it is necessary to verify the above clinical and laboratory parameters in the early stages of hospitalization.
