Sequence of actions for visualization of soft tissue hemorrhages/hematomas in elderly patients infected with SARS-CoV-2.

Aim. To determine ultrasound, computed tomography and angiographic image characteristics for soft tissue hemorrhages/hematomas, the sequence of using imaging methods in patients infected with SARS-CoV-2, to study the morphology of changes in soft tissues, to determine the essence of the concept and to develop treatment tactics for this complication of COVID-19. Material and methods. During 4 months of treatment of elderly patients (+60) infected with SARS-CoV-2, 40 patients were identified with soft tissue hemorrhages/hematomas, of which 26 (65%) patients with large hematomas (>10 cm in size and > 1000 ml in volume). The analysis of clinical and laboratory parameters, methods of instrumental diagnostics (ultrasound - 26 patients, CT - 10 patients, angiography - 9 patients, punctures - 6 patients) was carried out;autopsy material was studied in 11 cases. Results. Image characteristics of hemorrhages/hematomas of soft tissue density were obtained using modern instrumental methods, and the sequence of application of visualization methods was determined. A tactic for managing a patient with stopped and ongoing bleeding has been developed. The morphological substrate of hemorrhagic complications in a new viral infection was studied. All patients were treated with conservative and minimally invasive procedures (embolization, puncture with pressure bandage). 15 patients (57.7%) recovered, 11 patients (42.3%) died from the progression of COVID-19 complications. Conclusion. Comprehensive clinical and laboratory sequential instrumental diagnosis of soft tissue hemorrhages in COVID-19. Treatment should be conservative and significantly invasive. The use of the term "soft tissue hematoma" in SARS-CoV-2 infected patients is not a natural quality of the normal pathological process and should not be observed from our point of view.Copyright © 2022 Rostovskii Gosudarstvennyi Meditsinskii Universitet.

Gastrointestinal stromal tumors in elderly patients

Background: Gastrointestinal stromal tumors (GISTs) account for 1 to 3% of all primary malignant tumors of the gastrointestinal tract. The global incidence of GISTs varies in the range of 7-15 cases per 1 million people per year. In about 95% of cases, the incidence is sporadic. Despite the fact that some success has been achieved in the treatment of this pathology, the problem of GISTs treatment is urgent, especially in elderly and senile patients in particular. The aim of the study: To study the age-related characteristics of GISTs development in patients of older age groups. Material(s) and Method(s): A retrospective analysis of 56 clinical cases of GISTs in patients of different age groups according to the WHO classification was carried out in the study. Result(s): The most common variant of the immunohistochemical structure was the spindle cell one 62.5%. In most cases, tumors were localized in the stomach 82.2%. Elderly patients had larger tumor sizes compared with young and middle-Aged patients. In patients of older age groups, the disease was most often detected at stage II. In most cases, a comorbid pathology was detected, most often a combination of several diseases of the cardiovascular system. Conclusion(s): In patients of older age groups, the spindle cell structure of the GISTs is most common, the tumor was most often localized in the stomach (77.4%), most often the tumor was localized along the lesser curvature. In most cases, the tumor was up to 10.0 cm in diameter. On average, the disease was detected at stage II. Comorbid pathology occurred in 87.3% of cases. In 2020-2021, the disease was detected more often, the of tumors sizes were smaller, due to an increase in the number of CT scans of the chest for the diagnosis of the new coronavirus infection.Copyright © 2022 AME Publishing Company.

Effectiveness of the vaccines against SARS-CoV-2 used in Spain: infection, hospitalization and mortality in people aged fifty to fifty-nine years

In this paper we compared brand-specific COVID-19 vaccine effectiveness (VE) during August 2021 in persons born 1962-1971 and vaccinated during June. For SARS-CoV-2 symptomatic infection, protection was lower for Janssen (56%;CI95%: 53-59) or AstraZeneca [Vaxzevria] (68%;CI95%: 65-70), compared to Pfizer-BioNTech [Comirnaty] (78%;CI95%: 77-78), AstraZeneca/Pfizer (86%;CI95%: 80-90) or Moderna [Spikevax] (89%;CI95%: 88-90). VE against hospitalization was ranged 86% for Janssen to 97%-98% for other vaccines.

Evolution and prognostic factors associated with mortality in older adults hospitalized for COVID-19

Background: SARS-CoV-2 affects all age groups, but higher mortality rates are recorded in older people, men and with comorbidities, mainly hypertension, diabetes and obesity. Aim: To describe the main clinical characteristics, evolution and prognostic factors for death in older patients hospitalized for COVID-19. Materials and methods: Retrospective analysis of 128 Patients aged 73 years, 66% men, hospitalized at a clinical hospital, with a diagnosis of COVID-19, admitted from May 1 to August 1, 2020. Data were collected from the clinical records, a description of the study population was made, and a univariate analysis and logistic regression were performed. Results: Seventy-two percent of patients had two or more comorbidities, mainly arterial hypertension in 66%, diabetes mellitus in 34% and cardiovascular disease in 19%. Forty-one percent were admitted to intensive care and 31% were connected to mechanical ventilation. In-hospital mortality was 26.6%. A multivariate analysis was performed in two blocks, finding in the first that arterial hypertension and older age significantly predict mortality. However, when previous institutionalization and immunosuppression were included as variables in the second block, age ceased to be a significant predictor. Conclusions: Prognostic factors associated with death in this age group are arterial hypertension and previous institutionalization.

Epidemiology of pandemic COVID-19 and its association with some chronic diseases in Sulaimani city, Iraq

The study aims to provide the epidemiological characteristics of the COVID-19 patients who admitted to Shahid Dr Hemin Teaching Hospital in Sulaimani city, Iraq. It is a cross-sectional study, the data were collected by a convenience sampling method in the hospital, which started from 2nd October to 31th of December 2020. The current study included all the patients who admitted to the hospital, which involved 371 patients. The data were collected from patient's medical record and a direct interview method was used for filling in the questionnaire form. The collected data were analysed by the SPSS program to produce descriptive statistics such as frequency, percentage, mean and standard deviation while Chi-square test used to find out the association between variables with considering a p-value 0.05 as a significant interpretation. The results show that the age of hospitalized COVID-19 patients ranges from 19-95 years old with mean of (63.69..12.73). The age of majority of patients 159 (42.9%) was between 65-79 years old followed by 50-64 years old 124 (33.4%). Male to female ratio was 2:1. Most of the patients were retired 119 (32.1%) in comparison to other occupations and illiterate patients 151(40.7%) were dominance over other patient's education levels. In addition, majority of patients had hypertension 278(74.9%), diabetes 132 (35.6%) and cardiovascular disease (CVD) 130 (35.0%) and 230 (62.0%) and 141(38.0%) of them were in severe and moderate stage of disease respectively. Also, there was a significant association between the patient's age group and patients' outcome while for gender, occupation, and education level, stage of the disease, there were non-significant. The presence of CVD, hypertension and diabetes increase the mortality rate among the patients. In conclusion, age of COVID-19 patient has a great impact on increasing mortality rate and the presence of comorbidities among the patients significantly raise the mortality rate of COVID-19.

Surveillance of COVID-19 in long-stay centers: the effect of the pandemic in nursing homes

This report shows the epidemiological situation of COVID-19 in the long-term care facilities (LTCF) for elderly throughout 2021 and until the 17th week of 2022. Since its start-up in January 2021, this surveillance has provided aggregated national weekly data, with information on the proportion of LTCF for elderly affected by COVID-19, the incidence of COVID-19 and fatal cases among a vulnerable population where the effects of the pandemic have been and are being especially severe. The comparison with the incidence and mortality of COVID-19 cases in noninstitutionalized elderly shows how the impact of COVID-19 is being greater among the elderly living in nursing homes, with more fatal cases than the rest of the population of the same age.

A case of a 107-year-old elderly COVID-19 patient infected with omicron variant BA.5.1.3 in Hainan

Objective This article summarizes the clinical characteristics and diagnosis and treatment experience of an elderly patient infected with Omicron variant BA.5.1.3 of COVID-19 in Hainan Province. Methods The clinical data and treatment of an elderly patient infected with Omicron variant BA.5.1.3 of COVID-19 admitted to Haikou designated hospital on August 15, 2022 were retrospectively analyzed. Results A 107-year-old female patient was admitted to the hospital with "fever and cough for 1 day". Two of her family members have infected with COVID-19. The patient initially developed fever, accompanied by cough, expectoration, a little white sticky sputum, accompanied by sore throat, muscle pain, fatigue. Nucleic acid test was positive in throat swab, indicating Omicron variant BA.5.1.3 infection. The patient was diagnosed as mild COVID-19 and treated with antiviral therapy, Chinese medicine conditioning, anticoagulation, electrolyte disorder regulation and symptomatic treatment for 9 days. The patient's clinical symptoms were relieved, and she was cured and discharged after two negative nucleic acid tests. One week later, the patient recovered well. Conclusions Omicron variant BA.5.1.3 is highly infectious, and comprehensive treatment such as antiviral treatment and traditional Chinese medicine treatment has achieved good efficacy. For elderly patients, attention should be paid to maintaining the stability of organ function and internal environment, which is helpful to improve the prognosis of patients.

Clinical significance of serum interleukin 6 in elderly patients infected with severe acute respiratory syndrome Coronavirus 2 Omicron variant and its correlation with underlying diseases

Objective: To investigate the clinical significance of serum interleukin 6 (IL-6) in elderly patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) omicron variant and its correlation with underlying diseases. Methods: A total of 22 elderly patients (> 80 years old) infected with omicron variant, who were admitted to Department of Infectious Diseases, The First Affiliated Hospital of Naval Medical University (Second Military Medical University) from Apr. to Jun. 2022 and tested positive for SARS-CoV-2 RNA, were included. The level of serum IL-6 was measured by flow cytometry, and the level of serum C reactive protein (CRP) was measured by immunonephelometry. Patients were divided into pneumonia group (16 cases) and non-pneumonia group (6 cases) according to the imaging examination results, and were divided into severe group (severe and critical type, 5 cases) and non-severe group (mild and normal type, 17 cases) according to the condition. Binary logistic regression model and receiver operating characteristic (ROC) curve were used to analyze the correlation between serum IL-6 and CRP levels and the severity of the disease and whether it would progress to pneumonia. Meanwhile, the relationships between underlying diseases and serum IL-6 level were explored. Results: Among the 22 patients, 6 were mild, 11 were normal, 3 were severe, and 2 were critical. The baseline serum IL-6 level in the pneumonia group was significantly higher than that in the non-pneumonia group ([20.16+or-12.36] pg/mL vs [5.42+or-1.57] pg/mL, P=0.009), and there was no significant difference in baseline serum CRP level between the 2 groups (P > 0.05). There were no significant differences in baseline serum IL-6 or CRP levels between the severe group and the non-severe group (both P > 0.05). Logistic regression analysis showed that the baseline serum IL-6 and CRP might be related to pneumonia after infection with omicron variant (odds ratio [OR]=2.407, 95% confidence interval [CI] 0.915-6.328;OR=1.030, 95% CI 0.952-1.114). ROC curve analysis showed that the area under curve values of serum IL-6 and CRP in predicting the progression to pneumonia were 0.969 (95% CI 0.900-1.000) and 0.656 (95% CI 0.380-0.932), respectively, with statistical significance (Z=2.154, P=0.030). There were no significant differences in the baseline serum IL-6 level or proportions of severe patients or pneumonia patients among patients with or without hypertension, diabetes mellitus, coronary heart disease, chronic kidney disease or chronic obstructive pulmonary disease (all P > 0.05). The baseline serum IL-6 levels of the omicron variant infected elderly patients with 1, 2, and 3 or more underlying diseases were 12.50 (9.15, 21.75), 23.55 (9.63, 50.10), and 10.90 (5.20, 18.88) pg/mL, respectively, with no statistical significance (P > 0.05). Conclusion: For omicron variant infected patients, serum IL-6 level is significantly increased in patients with pneumonia manifestations and is correlated with disease progression. Serum IL-6 level is of great guiding significance to judge disease progression and evaluate efficacy and prognosis of elderly coronavirus disease 2019 patients.

The COVID-19 pandemic spread on hospital admissions in the Bolzano Province (Italy): a descriptive study (February 2020-March 2022)

Introduction: Italy was one of the first countries to be affected because of a severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2) due to COVID-19 infection. However, the cases spread has not been consistent, featuring different tendencies over the months: in some periods cases escalated speedily and in others their expansion was indeed under restraint. Materials and methods: Based on Kaplan-Meier survival curves, the descriptive study includes the COVID-19 hospitalization in the Bolzano Province from February 2020 to March 2022 to analyze the frequency of such hospitalizations and the association between risk factors as age, sex, pandemic's wave, and the 30-day in-hospital mortality. Results: According to the results, starting from the first hospitalization, the 91.6% of in-hospital deaths occurred within 30 days, with an estimated 30-day's survival probability of 0.675 (95% CI: 0.649-0.699) for patients over 85 years of age;the estimate for male patients is 0.833 (95% CI: 0.820-0.846) and that for patients admitted during the initial wave is to 0.784 (95% CI: 0.751-0.813). Discussion and conclusions: The results of the study are in line with other studies in the literature at national and international level supporting the hypothesis that the rising age, the male sex and the first wave have played an important role in the COVID-19 mortality rate.

Analysis of related factors of nucleic acid shedding in elderly patients infected with Omicron variant of SARS-CoV-2

Objective: To analyze the nucleic acid shedding time of Omicron variant of novel coronavirus in the elderly patients with non-severe infection, and to explore the related factors affecting the nucleic acid shedding time. Methods: A total of 104 elderly patients with non-severe COVID-19 were divided into early negative group (<10 days) and late negative group ( 10 d) by the nucleic acid shedding time. The population information, vaccination, previous diseases, blood biochemical and inflammatory indicators, nucleic acid ORFIab gene and N gene Ct values were collected and compared between the two groups. The Spearman rank correlation and multiple linear regression were conducted to explore the influencing factors of the nucleic acid shedding time. Results: The mean time of nucleic acid shedding of Omicron variant in the early negative group was 7.26: 1.54 d, compared with 12.96: 2.44 d in the late negative group. There were significant differences in age, the ratio of chronic heart failure, chronic pulmonary disease and booster vaccination for COVID-19 and the first nucleic acid Ct value between the two groups (P < 0.05). Spearman correlation analysis showed that the nucleic acid shedding time of Omicron was positively correlated with age, chronic heart failure and serum level of procalcitonin, but negatively correlated with the vaccination booster and the first tested nucleic acid Ct value. Multiple linear regression analysis showed that age, vaccination booster and the first tested nucleic acid Ct value were the independent influencing factors of the nucleic acid shedding time. Conclusions: Age, vaccination booster for COVID-19 and the first tested nucleic acid Ct value were the independent influencing factors of nucleic acid shedding in [the elderly non-severe patients infected by SARS-CoV-2 Omicron. Vaccination booster for COVID-19 in the elderly vulnerable groups can shorten the time of nucleic acid shedding.

Deep Venous Thrombosis in Elderly Inpatients with Pneumonia

Background: The occurrence of deep vein thrombosis (DVT) in COVID-19 pneumonia has raised wide concern recently, but few studies have reported the incidence of DVT in other types of pneumonia. We evaluate the prevalence, risk factors and treatment of DVT in the elderly inpatients with pneumonia. Method(s): A cohort of 550 elderly inpatients (>= 75 years old) with pneumonia between 2017 and 2021 were reviewed. They were divided into DVT group and non-DVT groups on the basis of whether pneumonia was combined with new-found DVT. Clinical data were collected retrospectively. Patients with DVT were divided into anticoagulant group and non-anticoagulant groups on the basis of whether they received anticoagulant therapy. Result(s): Ninety-seven patients were included in the DVT group;453 in the non-DVT group. The incidence of DVT was 17.64%. Hospital stays were significantly longer for DVT patients than for non-DVT counterparts (p = 0.005). Coronary heart disease, heart failure, hyperlipidemia, bed rest, and elevated D-dimer were independent risk factors for DVT (p < 0.05). The rate of anticoagulant therapy in DVT group was 63.92% (62/97 cases). Follow-up showed that the continuous anticoagulant treatment rate was 48.39% (30/62 cases) at 3 months and 30.65% (19/62 cases) at 6 months. Conclusion(s): Elderly inpatients with pneumonia are at high risk of DVT. The combination of DVT and pneumonia may lead to prolonged hospitalization. Coronary heart disease, heart failure, hyperlipidemia, bed rest and elevated D-dimer are independent risk factors for DVT in these patients. The rate of regular anticoagulant treatment is low because of the high risk of bleeding.Copyright © 2022, Taiwan Society of Geriatric Emergency & Critical Care Medicine.

Clinical factors associated with adverse clinical outcomes in elderly versus non-elderly COVID-19 emergency patients: a multi-center observational study.

BACKGROUND: The COVID-19 pandemic has caused over 6 million deaths worldwide. The elderly accounted for a large proportion of patients with their mortality rate largely higher than the non-elderly. However, limited studies have explored clinical factors associated with poor clinical outcomes in this important population. Therefore, this study aimed to determine factors independently associated with adverse clinical outcomes among COVID-19 elderly patients. METHODS: We conducted a multicenter observational study at five emergency departments (EDs) in Thailand. Patients over 18 years old diagnosed with COVID-19 between January and December 2021 were included. We classified patients into elderly (age ≥ 65 years) and non-elderly (age < 65 years). The primary clinical outcome was in-hospital mortality. The secondary outcomes were endotracheal intubation and intensive care unit admission. We identified independent factors associating with these outcomes both in the whole population and separately by age group using multivariate logistic regression models. RESULTS: A total of 978 patients were included, 519 (53.1%) were elderly and 459 (46.9%) were non-elderly, and 254 (26%) died at hospital discharge. The mortality rate was significantly higher in the elderly group (39.1% versus 14.3%, p<0.001)). In the elderly, age (adjusted odds ratio (aOR) 1.13; 95% confidence interval (CI) 1.1-1.2; p<0.001), male sex (aOR 3.64; 95%CI 1.5-8.8; p=0.004), do-not-resuscitate (DNR) status (aOR 12.46; 95%CI 3.8-40.7; p<0.001), diastolic blood pressure (aOR 0.96; 95%CI 0.9-1.0; p=0.002), body temperature (aOR 1.74; 95%CI 1.0-2.9; p=0.036), and Glasgow Coma Scale (GCS) score (aOR 0.71; 95%CI 0.5-1.0; p=0.026) were independent baseline and physiologic factors associated with in-hospital mortality. Only DNR status and GCS score were associated with in-hospital mortality in both the elderly and non-elderly, as well as the overall population. Lower total bilirubin was independently associated with in-hospital mortality in the elderly (aOR 0.34; 95%CI 0.1-0.9; p=0.035), while a higher level was associated with the outcome in the non-elderly. C-reactive protein (CRP) was the only laboratory factor independently associated with all three study outcomes in the elderly (aOR for in-hospital mortality 1.01; 95%CI 1.0-1.0; p=0.006). CONCLUSION: Important clinical factors associated with in-hospital mortality in elderly COVID-19 patients were age, sex, DNR status, diastolic blood pressure, body temperature, GCS score, total bilirubin, and CRP. These parameters may aid in triage and ED disposition decision-making in this very important patient population during times of limited resources during the COVID-19 pandemic.

The antiviral activity of a small molecule drug targeting the NSP1-ribosome complex against Omicron, especially in elderly patients.

Introduction: With the emergence of SARS-CoV-2 mutant strains, especially the epidemic of Omicron, it continues to evolve to strengthen immune evasion. Omicron BQ. 1 and XBB pose a serious threat to the current COVID-19 vaccine (including bivalent mRNA vaccine for mutant strains) and COVID-19-positive survivors, and all current therapeutic monoclonal antibodies are ineffective against them. Older people, those with multimorbidity, and those with specific underlying health conditions remain at increased risk of COVID-19 hospitalization and death after the initial vaccine booster. However, small-molecule drugs for conserved targets remain effective and urgently needed. Methods: The non-structural protein of SARS-CoV-2 non-structural protein 1(Nsp1) can bind to the host 40S ribosomal subunit and activate the nuclease to hydrolyze the host RNA, while the viral RNA is unaffected, thus hijacking the host system. First, the present study analyzed mutations in the Nsp1 protein and then constructed a maximum-likelihood phylogenetic tree. A virtual drug screening method based on the Nsp1 structure (Protein Data Bank ID: 7K5I) was constructed, 7495 compounds from three databases were collected for molecular docking and virtual screening, and the binding free energy was calculated by the MM/GBSA method. Results: Our study shows that Nsp1 is relatively conserved and can be used as a comparatively fixed drug target and that therapies against Nsp1 will target all of these variants. Golvatinib, Gliquidone, and Dihydroergotamine were superior to other compounds in the crystal structure of binding conformation and free energy. All effectively interfered with Nsp1 binding to 40S protein, confirming the potential inhibitory effect of these three compounds on SARS-CoV-2. Discussion: In particular, Golwatinib provides a candidate for treatment and prophylaxis in elderly patients with Omicjon, suggesting further evaluation of the anti-SARS-CoV-2 activity of these compounds in cell culture. Further studies are needed to determine the utility of this finding through prospective clinical trials and identify other meaningful drug combinations.

A Systematic Review of Lung Autopsy Findings in Elderly Patients after SARS-CoV-2 Infection.

Although COVID-19 may cause various and multiorgan diseases, few research studies have examined the postmortem pathological findings of SARS-CoV-2-infected individuals who died. Active autopsy results may be crucial for understanding how COVID-19 infection operates and preventing severe effects. In contrast to younger persons, however, the patient's age, lifestyle, and concomitant comorbidities might alter the morpho-pathological aspects of the damaged lungs. Through a systematic analysis of the available literature until December 2022, we aimed to provide a thorough picture of the histopathological characteristics of the lungs in patients older than 70 years who died of COVID-19. A thorough search was conducted on three electronic databases (PubMed, Scopus, and Web of Science), including 18 studies and a total of 478 autopsies performed. It was observed that the average age of patients was 75.6 years, of which 65.4% were men. COPD was identified in an average of 16.7% of all patients. Autopsy findings indicated significantly heavier lungs, with an average weight of the right lung of 1103 g, while the left lung mass had an average weight of 848 g. Diffuse alveolar damage was a main finding in 67.2% of all autopsies, while pulmonary edema had a prevalence of between 50% and 70%. Thrombosis was also a significant finding, while some studies described focal and extensive pulmonary infarctions in 72.7% of elderly patients. Pneumonia and bronchopneumonia were observed, with a prevalence ranging from 47.6% to 89.5%. Other important findings described in less detail comprise hyaline membranes, the proliferation of pneumocytes and fibroblasts, extensive suppurative bronchopneumonic infiltrates, intra-alveolar edema, thickened alveolar septa, desquamation of pneumocytes, alveolar infiltrates, multinucleated giant cells, and intranuclear inclusion bodies. These findings should be corroborated with children's and adults' autopsies. Postmortem examination as a technique for studying the microscopic and macroscopic features of the lungs might lead to a better knowledge of COVID-19 pathogenesis, diagnosis, and treatment, hence enhancing elderly patient care.

COVID-19 in Elderly Patients Receiving Haemodialysis: A Current Review.

There is an increased incidence of elderly adults diagnosed with kidney failure as our global aging population continues to expand. Hence, the number of elderly adults indicated for kidney replacement therapy is also increasing simultaneously. Haemodialysis initiation is more commonly observed in comparison to kidney transplantation and peritoneal dialysis for the elderly. The onset of the coronavirus 2019 (COVID-19) pandemic brought new paradigms and insights for the care of this patient population. Elderly patients receiving haemodialysis have been identified as high-risk groups for poor COVID-19 outcomes. Age, immunosenescence, impaired response to COVID-19 vaccination, increased exposure to sources of COVID-19 infection and thrombotic risks during dialysis are key factors which demonstrated significant associations with COVID-19 incidence, severity and mortality for this patient group. Recent findings suggest that preventative measures such as regular screening and, if needed, isolation in COVID-19-positive cases, alongside the fulfillment of COVID-19 vaccination programs is an integral strategy to reduce the number of COVID-19 cases and consequential complications from COVID-19, particularly for high-risk groups such as elderly haemodialysis patients. The COVID-19 pandemic brought about the rapid development and repurposing of a number of medications to treat patients in the viral and inflammatory stages of their disease. However, elderly haemodialysis patients were grossly unrepresented in many of these trials. We review the evidence for contemporary treatments for COVID-19 in this population to provide clinicians with an up-to-date guide. We hope our article increases awareness on the associations and impact of COVID-19 for the elderly haemodialysis population, and encourage research efforts to address knowledge gaps in this topical area.

Reduction in the number of neutrophils in the broncho-alveolar aspirate is associated with worse prognosis in elderly patients with severe COVID-19.

The blood levels of neutrophils are associated with the severity of COVID -19. However, their role in the pulmonary environment during COVID -19 severity is not clear. Here, we found a decrease in the neutrophil count in BAL (bronchoalveolar lavage) in non-survivors and in older patients (> 60 years). In addition, we have shown that older patients have higher serum concentration of CXCL8 and increased IL-10 expression by neutrophils.

Perception and Attitude Towards COVID-19 Vaccination Among the Elderly: A Community-Based Cross-Sectional Study.

Introduction COVID-19 is one of the most formidable obstacles that humanity has encountered in this century. The death rate was high among the elderly in India; therefore, getting the elderly vaccinated was one of the most important things to do. Objective We conducted this study to assess the perception and attitude about the COVID-19 vaccines among the elderly population. Methods This cross-sectional study was conducted at Fatehpur Beri, New Delhi. We selected 108 participants using systematic random sampling. We used a semi-structured questionnaire to collect the data. Results Out of 108 participants, 52.8% were men. Among them, 9.3% of participants had tested positive before. The average number of days of illness among the participants was 5.3 (SD + 3.5). Males had a higher average day of illness (5.5, SD +3.7) than females (4.9, SD +3.3). Among those who had not been vaccinated, 73.3% of participants said they would receive the vaccine, 6.7% were unsure, and 20% were not willing to receive the vaccine. Conclusion COVID vaccination in an elderly population showed a relatively high vaccine acceptance rate, and the willingness to get the vaccine was also high among the unvaccinated.

Outcomes of Elderly Patients Hospitalized with the SARS-CoV-2 Omicron B.1.1.529 Variant: A Systematic Review.

The Omicron (B.1.1.529) variant of the severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) had an increased rate of spreading among the general population. Although this virus mutation resulted in milder symptoms, those on the vulnerable side of the population are still in danger of developing severe symptoms. Thus, this systematic review focused on identifying the clinical outcomes of older age patients (>65) that are hospitalized with the SARS-CoV-2 Omicron variant. The research was conducted using four electronic databases (PubMed, Scopus, Web of Science, and ProQuest Central), with a search query in December 2022 that comprised the duration of the COVID-19 pandemic. The inclusion criteria comprised (1) a population of patients older than 65 years, (2) a history of hospitalization for SARS-CoV-2 infection, and (3) infection with Omicron B.1.1.529 variant. The initial search generated 295 articles, out of which six were included in the systematic review, and a total of 7398 patients. The main findings were that when looking at the elderly population, the mortality and hospitalization rates remained high. This is because older people are more vulnerable and have more comorbidities that interfere with the virus's progress. However, there is inconsistency in mortality rates, since the data reported by the included studies had different selection criteria based on the severity of the COVID-19 infection. Although no statistically significant differences were found between the unvaccinated and vaccinated groups, patients who got booster doses of vaccination had a lower likelihood of developing severe symptoms, serving as a protective factor for this population.

Risk factors for postoperative medical morbidity and 3-month mortality in elderly patients with hip fracture following hip arthroplasty during COVID-19 pandemic.

BACKGROUND: The purpose of the current study was to investigate the incidence of postoperative medical complications and 3-month mortality in patients ≥ 70 years old with hip fracture following hip arthroplasty (HA) and independent risk factors associated with postoperative medical complications and 3-month mortality during the Coronavirus Disease 2019 (COVID-19) pandemic. METHODS: A multicenter retrospective study was conducted, patients ≥ 70 years old with HA for hip fracture under general anesthesia were included during COVID-19 and before COVID-19 pandemic. The outcome was defined as postoperative medical complications and 3-month mortality. The baseline characteristics and risk factors were collected, multivariable logistic regression was used to identify independent risk factors for postoperative medical complications and 3-month mortality. RESULTS: A total of 1096 patients were included during COVID-19 pandemic and 1149 were included before COVID-19 pandemic in the study. Patients ≥ 70 years with hip fracture for HA had longer fracture to operation duration (7.10 ± 3.52 vs. 5.31 ± 1.29, P < 0.001), and the incidence of postoperative medical complications (21.90% vs. 12.53%, P < 0.001) and 3-month mortality (5.20% vs. 3.22%, P = 0.025) was higher during COVID-2019 pandemic. Multivariate logistic regression analysis showed that dementia (OR 2.73; 95% CI 1.37-5.44; P = 0.004), chronic obstructive pulmonary disease (COPD) (OR 3.00; 95% CI 1.92-4.71; P < 0.001), longer fracture to operation duration (OR 1.24; 95% CI 1.19-1.30; P < 0.001) were associated with increased risk for postoperative medical complications. COPD (OR 2.10; 95% CI 1.05-4.17; P = 0.035), dementia (OR 3.00; 95% CI 1.11-7.94; P = 0.031), postoperative medical complications (OR 4.99; 95% CI 2.68-9.28; P < 0.001), longer fracture to operation duration (OR 1.11; 95% CI 1.04-1.19; P = 0.002) were associated with increased risk for 3-month mortality. CONCLUSIONS: In conclusion, we found that postoperative medical morbidity and 3-month mortality in patients with hip fracture underwent HA were 21.90% and 5.20%, respectively, during the COVID-19. COPD, dementia and longer fracture to operation duration were associated with negative outcome in patients with hip fracture underwent HA during the COVID-19.

Geriatric Sepsis in the COVID-19 Era: Challenges in Diagnosis and Management

The elderly or geriatric patients represent a significant portion of emergency department (ED) admissions. Factors affecting poor outcome in these patients suspected or diagnosed with sepsis include shock, hyperlactatemia, and organ failure. Atypical presentations should be emphasized in the training of triage and ED personnel due to difficulties and pitfalls in diagnostic processes for sepsis. The vital organ functions of the elderly, who are among the highest risk groups in the management of sepsis, may deteriorate rapidly with very few precursors, and aggressive methods should be used rapidly when necessary. Interactions of drug doses in the elderly, problems in excretion and differences in metabolism should be considered in treatment regimens. Healthcare workers should try to eliminate colonization risks such as vascular catheterization, unnecessary vascular access and urinary catheters should be removed.In the long term after recovery from sepsis, heart failure, peripheral vascular disease, dementia, and diabetes are the most common entities recorded in the literature. This review was intended to provide an overview of the overall management and give some practical tips for this fragile group of patients in the post-pandemic era.
