A Novel Nomogram Developed Based on Preoperative Immune Inflammation-Related Indicators for the Prediction of Postoperative Delirium Risk in Elderly Hip Fracture Cases: A Single-Center Retrospective Cohort Study.

Postoperative delirium (POD) commonly occurs in elderly individuals following hip fracture surgery, with unclear pathophysiological mechanism. Inflammation is a known factor affecting the onset of delirium. The current work aimed to examine the associations of preoperative immune inflammation-related indicators with POD occurrence in elderly cases following hip fracture surgery. The current retrospective cohort study included 437 elderly cases administered hip fracture surgery from January 2018 to December 2023. The clinicodemographic data and laboratory findings of all cases were retrospectively analyzed. Immune inflammation-related indicators were assessed, eg, MLR, NLR and PLR, as well as SII and SIRI. The bootstrap method was employed to assign cases at 7:3 to the training (48 and 258 cases in the POD and no-POD groups, respectively) and internal validation (13 and 118 cases in the POD and no-POD groups, respectively) cohorts. Next, LASSO, univariable and multivariable logistic regression analyses were applied to determine risk factors in the training cohort, based on which a nomogram model was built. The obtained nomogram was examined for accuracy by calibration plot analysis. Finally, the nomogram's clinical value was assessed by decision curve analysis (DCA), followed by internal validation based on the training cohort. Of all 437 cases, 61 developed POD, indicating a POD incidence of 13.96%. LASSO regression and multivariable analyses revealed preoperative SIRI independently predicted POD in the training cohort. The developed nomogram had an area under the curve (AUC) of 0.991 (95% CI 0.983~0.998) in the training cohort versus 0.986 (95% CI 0.966~1.000) in the validation cohort. Calibration curve analysis revealed nomogram-predicted and actual probabilities were in line. DCA demonstrated the novel nomogram could confer net benefits for POD prediction in elderly cases administered hip fracture surgery. The immune inflammation-related indicators SIRI could predict POD in elderly cases following hip fracture surgery.

Prevalence Characteristics of Osteoporosis Fractures in the Elderly in Two Regions of China and Analysis of the Lag Effect of Air Pollutants on them.

Air pollution is increasing and threatening human health. The objective of this study is to investigate the population distribution characteristics of elderly osteoporosis fractures in Hebei Province and Xinjiang Uygur Autonomous Region and to analyze the effects of air pollutants on the number of elderly osteoporosis fracture inpatients in the two regions. A retrospective collection of elderly osteoporosis fracture cases was conducted in selected hospitals in Hebei Province and Xinjiang Uygur Autonomous Region from January 1, 2018 to December 31, 2022. The chi-square test was used to compare the distributional characteristics of the population in the two regions. Additionally, we used a distributed lag nonlinear model (DLNM) in order to assess the effect of air pollutants on the number of daily hospital admissions of elderly osteoporosis fracture patients in different regions. A total of 19,203 elderly osteoporosis fracture patients were included in the study. The average age of these patients was 76.66 ± 7.55 years, and the majority of them were female (13,514 instances, 70.37%). The disparities in age distribution (χ2 = 133.9 p < 0.001), fracture site (χ2 = 62.0 p < 0.001), and hospitalization cost (Z = -15.635 p < 0.001) between the two regions were statistically significant. The lag effect curves of PM2.5, PM10, and NO2 on the number of elderly osteoporosis fracture hospitalizations in Xinjiang Uygur Autonomous Region exhibited a similar pattern resembling a "W"-shaped curve. All three pollutants reached their highest values after a lag time of 14 days (PM2.5: RR = 1.053, 95% CI: 1.031, 1.074; PM10: RR = 1.031, 95% CI: 1.018, 1.043; NO2: RR = 1.125, 95% CI: 1.070, 1.182). In Hebei Province, the largest impacts of PM2.5 and PM10 were observed after a lag of 14 days (PM2.5: RR = 1.022, 95% CI: 1.013, 1.028; PM10: RR = 1.013, 95% CI: 1.008, 1.018). Similarly, the maximum effect of NO2 was observed after a lag of 11 days (RR = 1.020, 95% CI: 1.010, 1.028). There were differences in the epidemiological characteristics of hospitalized patients with osteoporosis fractures between the two regions, PM2.5, PM10, and NO2 increased the number of hospitalizations for osteoporosis fractures. Exposure to air pollutants such as PM2.5 increases the risk of osteoporosis fractures in the elderly population.

Multidisciplinary treatment for bronchial adenoid cystic carcinoma: An elderly case

Epidemiological Aspects and Pattern of Intoxication among Elderly in Khorasan-Razavi; Northeast of Iran.

This study aimed to assess the risk factors and clinical-epidemiological patterns of acute poisoning among elderly individuals to guide prevention strategies. The epidemiological, clinical data, manner and cause of poisoning, and outcome of the registered elder cases (≥ 60 years old) in the clinical toxicology department of Imam Reza Hospital of Mashhad University of Medical Silences (CTD-IRH-MUMS) were investigated for nine months. The sex and age distribution of the patients were compared with the general population of Khorasan-Razavi using direct standardization. Among the 3064 cases registered at the hospital, 124 elderly patients were included in the study. The majority (71.8%) were male, with a mean age of 69.47. Male gender was found to be a significant risk factor for poisoning among elderly individuals compared to the general population (OR = 2.62) (1.55-4.42) (p-value < 0.001), however, it was not significant for age. Substance dependency, particularly on opiates, was common among the patients (56.5%), with a higher prevalence in males. Substance overdose (35.4%) and suicide (23.3%) were the most common methods of poisoning, with varying frequencies between genders (p-value = 0.002). Male gender was identified as a risk factor for opiate intoxication (OR = 4.68, CI = 1.70-11.83, p-value < 0.05) but not for suicide attempts. The average hospital stay duration was similar between male and female patients. The mean length of hospital stay was 3.53 ± 4.02 days (median = 3.0, range = 0.5-26 days) and was similar in both sexes. In conclusion,male gender and opiate dependency were highlighted as key factors in the poisoning of elderly individuals. These findings emphasize the importance of addressing these factors in preventive measures.

An elderly case of paraneoplastic anti-NMDA receptor encephalitis associated with large cell neuroendocrine carcinoma of the lung

BackgroundRecent studies have suggested that N-methyl-D-aspartate (NMDA) receptors are involved in the cell proliferation in several tumors. However, there have been no reports demonstrating the expression of NR1 subunit of the NMDA receptor in large cell neuroendocrine carcinoma (LCNEC).Case presentationHere, we report the first elderly case of paraneoplastic anti-NMDA receptor encephalitis associated with LCNEC of the lung with NR1 expression. Of note, NR1 subunit expression in the tumor cells of the present case was confirmed by immunohistochemistry (IHC). Radiation therapy and immunotherapies, such as corticosteroids and intravenous immunoglobulin (IVIG), shrank the tumors and improved neurological symptoms in the present case. Additionally, we also confirmed the expression of NR1 in the tumor cells obtained from three other cases with LCNEC of the lung at our hospital by IHC.ConclusionOur IHC results indicate that LCNEC generally expresses NR1 subunit and NMDA receptor may be involved in the tumor development and growth.

Campylobacteriosis is an Allied Disease in the Elderly

In this study we analysed campylobacteriosis cases in a tertiary care hospital of India to find out this is an isolated disease or an allied disease with comorbidities in elderly people. In all the four elderly cases, acute gastroenteritis by Campylobacter appears to be a contributory condition of the disease besides other associated diseases. Perceptive the link between this disease and comorbidities is crucial for effective prevention, early detection, and thorough care, in elderly populations with underlying health problems.

Epidemiological and clinical characteristics of respiratory syncytial virus infection among people aged 60 and above in Beijing City

Objective: To investigate the epidemiological and clinical characteristics of RSV among patients aged ≥60 years in Beijing from 2015 to 2023. Methods: Based on the respiratory pathogen surveillance system, samples of upper respiratory tract infections (URTI), non-severe community-acquired pneumonia (nsCAP) and severe community-acquired pneumonia (sCAP) among people aged ≥60 years were collected from 28 sentinel hospitals in 16 districts of Beijing from January 2015 to December 2023. Swab samples were collected from URTI within one week, and lower respiratory tract samples from nsCAP and sCAP were collected. Demographic and epidemiological data were also collected. Various respiratory pathogens including RSV were detected. Results: From January 2015 to December 2023, a total of 20 349 cases of acute respiratory infections aged ≥60 years were included, with the RSV-positive rate of 1.54% (313/20 349, 95%CI: 1.39%-1.68%). Among them, the total RSV-positive rates of older people during the pre-pandemic, pandemic, and post-pandemic periods of COVID-19 were 1.59% (207/13 006, 95%CI: 1.38%-1.81%), 0.82% (38/4 650, 95%CI: 0.56%-1.08%) and 2.53% (68/2 693, 95%CI: 1.93%-3.12%), respectively. The difference in RSV-positive rate was statistically significant (P<0.001). Based on the sampling time of cases, the RSV epidemic season for older people in Beijing was from October to March of the following year, with a peak period in December or January of the following year. In the post COVID-19 pandemic, there were very few RSV-positive cases detected in the elderly from April to June 2023, with only one positive case detected in May and one in June. The RSV-positive rate of older people increased significantly from October to December, reaching 11.75% (51/383) in December. Among 263 RSV-positive cases in the elderly, RSV-A, RSV-B and unclassified type accounted for 43.35% (114/263), 29.28% (77/263) and 27.38% (72/263), respectively. Since 2020, there has been a subtype conversion, with RSV-B being the main focus. Among 197 elderly cases that have complete clinical data, the main symptoms were cough (86.8%, 171/197), sputum (80.2%, 158/197) and fever (73.60%, 145/197). About 24.87% (49/197) of elderly cases experienced complications. The hospitalization mortality rate was 4.57% (9/197), and the hospitalization rate was 78.68% (155/197). The ICU occupancy rate was 1.99% (36/197). The mechanical ventilation usage rate was 13.32% (33/197), and the length of hospital stay [M (Q1, Q3)] was 12 (9, 16) days. Conclusion: In Beijing, the RSV infection rate is relatively low during the COVID-19 pandemic, and the prevalence of COVID-19 is relatively high. In 2023, there was no out-of-season outbreak of RSV infection among the elderly. Elderly RSV infection cases have multiple complications, severe diseases, and poor prognosis.

TBE in Bosnia and Herzegovina

Sequence analysis of respiratory syncytial virus cases reveals a novel subgroup -B strain circulating in north-central Italy after pandemic restrictions

BackgroundFollowing the pandemic restrictions, the epidemiology of respiratory syncytial virus (RSV) has changed, leading to intense hospitalization peaks. ObjectivesThis study, conducted at multiple sites in Italy, aimed to describe the temporal dynamics of two post-COVID-19 RSV epidemics. Additionally, the circulating RSV-A and -B lineages were characterized and compared to those found in 2018 and 2019. Study designRespiratory specimens and data were collected from RSV-positive patients, both inpatients, and outpatients, of all ages at three sites in north-central Italy. To analyze these samples, roughly one-sixth were sequenced in the attachment glycoprotein G gene and subjected to phylogenetic and mutational analyses, including pre-pandemic sequences from north-central Italy. ResultsThe first post-pandemic surge of RSV cases was quite intense, occurring from October 2021 to early January 2022. The subsequent RSV epidemic (from November 2022 to early March 2023) also had a high impact, characterized by a rise in elderly patient cases. Post-pandemic cases of RSV-A were caused by various strains present in Italy prior to COVID-19. In contrast, a distinct RSV-B lineage, which was concurrently spreading in other countries, was identified as the main cause of the surge in 2022–2023 but remained undetected in Italy before the pandemic. ConclusionsThis study describes the temporal dynamics of post-pandemic RSV subgroups and uncovers a lineage of RSV-B with high genetic divergence that may have increased the impact of decreased population immunity.

ASSOCIATION BETWEEN THE WEIGHT ADJUSTED WAIST INDEX AND INCIDENT STROKE

Objective: The association between weight-adjusted-waist index (WWI) and stroke is unclear. We aimed to determine the relationship of the WWI and stroke among the elderly patients with hypertension. Design and method: The Cox regression model was used to evaluate the relationship between baseline WWI and the risk of new-onset stroke. Restricted cubic splines were performed to explore the shape of the association between baseline WWI and stroke. Besides, we conducted subgroup analyses and interaction tests. Results: A total of 4962 hypertensive participants aged more than 60 years without a history of stroke were recruited in our study. During a median follow-up of 3.2 years, 547 incidents of new-onset stroke occurred. After adjusted for covariates, cox regression models showed the positive relationship between the baseline WWI and first stroke event. The hazard ratios (HRs) gradually increases, along with augment in WWI. Compared to the lowest quartile of WWI (Q1), HR and 95% confidence interval (CI) for stroke in the Q4 were 1.87 (1.44, 2.42). In stratified analyses, the association between WWI and the risk of stroke maintained. Conclusions: High WWI showed a positive association with new on-set stroke among elderly patients with hypertension. The rising prevalence of WWI may increase the future burden of stroke in elderly hypertensive cases.

Geriatric cutaneous leishmaniasis: a retrospective analysis of 622 cases.

Cutaneous leishmaniasis (CL) is most common in childhood because children are exposed to the parasite early and, unlike adults, do not have immunity to CL. Since CL is less common in geriatric patients, clinical and epidemiological data in this age group are limited. This study aims to compare the clinical and demographic characteristics of geriatric patients diagnosed with CL with young patients. In this retrospective study, 622 patients aged 65 and over and 6350 patients aged 19-64, who applied to Şanlıurfa Oriental Boil Diagnosis and Treatment Center between January 2013 and February 2024 and were diagnosed with CL by parasitological examination, were included. Clinical and demographic characteristics of patients diagnosed with CL, such as age, gender, location of the lesion, lesion size, duration of the lesion, and treatments applied due to the diagnosis of CL, were recorded. Clinical and demographic characteristics of geriatric and young patients were compared. The mean age of elderly CL cases was 72.95 ± 6.54years, and 65.2% were female. The most common clinical forms were ulcers (51.9%) and plaques (41%), respectively, in young and elderly patients. The most common locations of the lesions were upper limbs (54.8%) in all patients. The most preferred treatment method was intralesional (IL) meglumine antimoniate (MA) treatment (98.3%) in all patients. There were no difference between young and elderly CL cases in terms of mean number of lesions, average lesion duration, average lesion size, lesion location, clinical forms of lesions, and treatments options (P > 0.05). Based on the results of our study, it can be said that the clinical and demographic characteristics of CL are similar in young and old patients and systemic MA treatment shows similar clinical benefit in both age groups. In addition, it can be said that systemic MA therapy can be used safely in young patients and elderly patients without contraindications. IL MA therapy can be used in elderly patients where systemic MA therapy is contraindicated.

Multidimensional features of sporadic Creutzfeldt-Jakob disease in the elderly: a case report and systematic review.

As a rare neurodegenerative disease, sporadic Creutzfeldt-Jakob disease (sCJD) is poorly understood in the elderly populace. This study aims to enunciate the multidimensional features of sCJD in this group. A case of probable sCJD was reported in a 90-year-old Chinese man with initial dizziness. Then, available English literature of the elderly sCJD cases (aged 80 years and over) was reviewed and analyzed. Patients (15 cases) were subdivided and compared geographically. In the elderly sCJD cohort, the onset age was 84.9 ± 4.5 years and the median disease duration was 6.8 months, with respiratory infection/failure as the commonest death cause. Various clinical symptoms were identified, with cognitive disorder (86.7%) as the commonest typical symptom and speech impairment (66.7%) as the most atypical one. Restricted hyperintensities were reported in 60.0% cases on DWI, periodic sharp wave complexes in 73.3% cases on electroencephalogram, and cerebral hypoperfusion/hypometabolism in 26.7% cases on molecular imaging. The sensitive cerebrospinal fluid biomarkers were total tau (83.3%), 14-3-3 protein (75.0%), and PrP RT-QuIC (75.0%). Neuropathological profiles in the cerebral cortex revealed vacuolar spongiosis, neuronal loss, gliosis, and aging-related markers, with synaptic deposit as the commonest PrP pattern (60.0%). The polymorphic PRNP analysis at codon 129 was M/M (90.9%), with MM1 and MM2C as the primary molecular phenotypes. Latency to first clinic visit, hyperintense signals on DWI, and disease duration were significantly different between the patient subgroups. The characteristics of sCJD are multidimensional in the elderly, deepening our understanding of the disease and facilitating an earlier recognition and better care for this group.

Heterogeneity in families with ATTRV30M amyloidosis: a historical and longitudinal Portuguese case study impact for genetic counselling

Background Hereditary transthyretin amyloidosis (ATTRv amyloidosis) is an inherited disease, where the study of family history holds importance. This study evaluates the changes of age-of-onset (AOO) and other age-related clinical factors within and among families affected by ATTRv amyloidosis. Methods We analysed information from 934 trees, focusing on family, parents, probands and siblings relationships. We focused on 1494 female and 1712 male symptomatic ATTRV30M patients. Results are presented alongside a comparison of current with historical records. Clinical and genealogical indicators identify major changes. Results Overall, analysis of familial data shows the existence of families with both early and late patients (1/6). It identifies long familial follow-up times since patient families tend to be diagnosed over several years. Finally, results show a large difference between parent-child and proband-patient relationships (20–30 years). Conclusions This study reveals that there has been a shift in patient profile, with a recent increase in male elderly cases, especially regarding probands. It shows that symptomatic patients exhibit less variability towards siblings, when compared to other family members, namely the transmitting ancestors’ age of onset. This can influence genetic counselling guidelines.

Aging and comprehensive molecular profiling in acute myeloid leukemia

Acute myeloid leukemia (AML) is an aging-related and heterogeneous hematopoietic malignancy. In this study, a total of 1,474 newly diagnosed AML patients with RNA sequencing data were enrolled, and targeted or whole exome sequencing data were obtained in 94% cases. The correlation of aging-related factors including age and clonal hematopoiesis (CH), gender, and genomic/transcriptomic profiles (gene fusions, genetic mutations, and gene expression networks or pathways) was systematically analyzed. Overall, AML patients aged 60 y and older showed an apparently dismal prognosis. Alongside age, the frequency of gene fusions defined in the World Health Organization classification decreased, while the positive rate of gene mutations, especially CH-related ones, increased. Additionally, the number of genetic mutations was higher in gene fusion-negative (GF-) patients than those with GF. Based on the status of CH- and myelodysplastic syndromes (MDS)-related mutations, three mutant subgroups were identified among the GF- AML cohort, namely, CH-AML, CH-MDS-AML, and other GF- AML. Notably, CH-MDS-AML demonstrated a predominance of elderly and male cases, cytopenia, and significantly adverse clinical outcomes. Besides, gene expression networks including HOXA/B, platelet factors, and inflammatory responses were most striking features associated with aging and poor prognosis in AML. Our work has thus unraveled the intricate regulatory circuitry of interactions among different age, gender, and molecular groups of AML.

Healthier Body Composition with High Phase Angle (PhA) In an Early Elderly Case by Blood Flow Restriction (BFR) Training

Demographic study of patients' mortality rate before and after the COVID-19 outbreak: A cross-sectional study.

To better guide the health policies, it is essential to clarify the socio-demographic and clinical risk factors affecting the mortality rate of patients with coronavirus disease 2019 (COVID-19). The purpose of this project is to separate hospital mortality statistics into different groups, which will definitely help in planning to reduce the mortality rate. As well, we aimed to compare factors involved in COVID-19 death between the period before and after its outbreak. This cross-sectional study was performed based on all death certificates of archived records in Rasool Akram Hospital during the years 2018 and the first half of 2019. A checklist was completed based on the variables, including death cases by time, gender, age, duration of hospitalization, department of place and time of death, cause of death, cases referred to forensic medicine, information of the patient, including educational and occupational level and birth certificate issuing city, neonatal death, and IUFD, classification of diseases according to the provided version of ICD 10 (international classification of diseases 10th edition). A number of 2632 deceased patients were included in this study, 1511 (57.4%) patients who died before the start of the COVID-19 outbreak, and 1121 (42.6%) patients died in the hospital after the start of this pandemic. There were statistically significant differences in gender (higher prevalence of males), increased average age, lower occupational status, decreased number of infants, increased cause of death due to COVID-19 and increased hospitalization in Royal ICU in dead patients (p < 0.05). The findings show that the elderly cases are more at risk of COVID-19 mortality than other age groups, which needs more attention to this group of society and clarifies other epidemiological factors, as well as clinicopathological and public healthcare practices.

A Study of Clinical and Socio-Demographic Profile of Elderly Patients with Opioid Use Disorder on Agonist Treatment Attending a Tertiary Care Teaching Institute of India

Background: Opioid use is one among the major substance of use in Indian population which is not only seen in younger age group but rather is an upcoming concern in the elderly population as well. Opioid agonist treatment for opioid use disorder is a better way of management, among which buprenorphine is a safer option. Despite, being an important area of health concern, opioid use is poorly studied in the geriatric population. Objective: To study the clinical and socio-demographic profile of elderly patients with opioid use disorder on agonist treatment attending a tertiary care teaching institute of urban Delhi. Method: A retrospective study was done in an OPD based opioid treatment centre of a tertiary care hospital in Delhi to analyze the socio-demographic, clinical profile, pattern of opioid use disorder and opioid agonist treatment (Buprenorphine) in elderly Indian population over a year. The data collected was further analyzed for descriptive and analytic statistics using SPSS version 23.0. Results: A total of 32 subjects of age &gt; 60years, with predominant male population having mean age of 63.6years we seen. They had heroin use by inhalation route as a major opioid use. The main source of referral was by friends and self with significant medical and psychiatric comorbidities that was seen in the elderly group. An average dose of 2.34mg of Buprenorphine was found to effectively manage the geriatric opioid use disorder. Conclusion: Opioid Used Disorder is common in Geriatric population and is often associated with both psychiatric and medical co-morbidities. Opioid agonist treatment is an effective approach in management of elderly cases of opioid use disorder. Declaration of Interest : None

Analysis of the Efficacy of Flexible Ureteroscopy and Rigid Ureteroscopy with Holmium Laser Lithotripsy in the Treatment of Upper Ureteral Stones in the Elderly

Objective: To compare the clinical efficacy of rigid ureteroscopy and flexible ureteroscopy with holmium laser lithotripsy in elderly patients with upper ureteral stones. Methods: 12 elderly cases of upper ureteral stones were selected and divided into two groups according to the type of surgery. The control group and the observation group adopted rigid ureteroscopic holmium laser lithotripsy and flexible ureteroscopic holmium laser lithotripsy, respectively. General observation indicators, laboratory indicators, and short-term efficacy-related indicators of surgery were compared between the two groups. Results: The operation time, ambulation time, and hospitalization time of the observation group were shorter than those of the control group, and the intraoperative blood loss was less than that of the control group (P &lt; 0.05). There was no significant difference in the total primary/secondary stone clearance rate, postoperative complications, and disease recurrence rate after six months of follow-up in the two groups (P &gt; 0.05). Conclusion: Compared with rigid ureteroscopic holmium laser lithotripsy, flexible ureteroscopic holmium laser lithotripsy for elderly patients with upper ureteral stones is more conducive to shortening the treatment and postoperative recovery time, and simultaneously, it causes no severe complications and is worthy of promotion.

Inflammatory and nutritional markers predict the risk of post-operative delirium in elderly patients following total hip arthroplasty.

This study intended to explore whether albumin-associated inflammatory and nutritional markers could predict post-operative delirium (POD) in older patients after total hip arthroplasty (THA). In addition, we established a nomogram model for POD prediction. Totally, 254 elderly cases who received THA were included. Clinical and laboratory data of these patients were retrospectively collected. Albumin-associated inflammatory and nutritional markers included neutrophil-to-albumin ratio (NAR), CRP-to-albumin ratio (CAR), prognostic nutritional index (PNI), and systemic inflammation score (SIS). The LASSO, univariate and multivariate logistic regression analyses were utilized to screen risk factors. A nomogram model was developed according to the results of multivariate regression analyses. Among 254 patients, 49 cases had POD with an incidence of 19.3%. LASSO regression and multivariate logistic analyses suggested that preoperative NAR, preoperative PNI, preoperative SIS, and age >75 years were risk factors for POD. A nomogram model was developed according to the results of multivariate logistic analyses. The calibration curve suggested that the predicted probability of this nomogram model was in good line with the actual probability. The DCA showed that this nomogram model had net benefits for the prediction of POD for elderly patients following THA. Albumin-associated inflammatory and nutritional markers including NAR, PNI, and SIS could predict POD in elderly patients following THA.
