BACKGROUND Coronavirus disease 2019(COVID-19),caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),has led to millions of confirmed cases and deaths worldwide.Elderly patients are at high risk of developing and dying from COVID-19 due to advanced age,decreased immune function,intense inflammatory response,and comorbidities.Shanghai has experienced a wave of infection with Omicron,a new variant of SARS-CoV-2,since March 2022.There is a pressing need to identify clinical features and risk factors for disease progression among elderly patients with Omicron infection to provide solid evidence for clinical policy-makers,public health officials,researchers,and the general public.AIM To investigate clinical characteristic differences and risk factors between elderly patients with severe and nonsevere Omicron SARS-CoV-2 variant infection.METHODS A total of 328 elderly patients with COVID-19 admitted to the Ninth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from April 2022 to June 2022 were enrolled and divided into a severe group(82 patients)and a nonsevere group(246 patients)according to the diagnosis and treatment protocol of COVID-19(version 7).The clinical data and laboratory results of both groups were collected and compared.A chi-square test,t test,Mann-Whitney U test,hierarchical log-rank test,univariate and multivariate logistic regression,and hierarchical analyses were used to determine significant differences.RESULTS The severe group was older(84 vs 74 years,P<0.001),included more males(57.3%vs 43.9%,P=0.037),had a lower vaccination rate(P<0.001),and had a higher proportion of comorbidities,including chronic respiratory disease(P=0.001),cerebral infarction(P<0.001),chronic kidney disease(P=0.002),and neurodegenerative disease(P<0.001),than the nonsevere group.In addition,severe disease patients had a higher inflammatory index(P<0.001),greater need for symptomatic treatment(P<0.001),longer hospital stay(P=0.011),extended viral shedding time(P=0.014),and higher mortality than nonsevere disease patients(P<0.001).No difference was observed in the application of Paxlovid in the severe and nonsevere groups(P=0.817).Oxygen saturation,cerebral infarction,and D-dimer were predictive factors for developing severe disease in patients with COVID-19,with D-dimer having an excellent role(area under the curve:90.1%,95%CI:86.1-94.0%).In addition,D-dimer was a risk factor for developing severe COVID-19 according to multivariate stratified analysis.CONCLUSION The clinical course of severe COVID-19 is complex,with a higher need for symptomatic treatment.D-dimer is a suitable biomarker for identifying patients at risk for developing severe COVID-19. 展开更多

Objective:To explore factors related to postoperative pulmonary infection in lung cancer patients after recovery from COVID-19 and to provide methods for preventing and reducing the incidence of postoperative lung infection in patients with lung cancer.Methods:A total of 92 patients who underwent lung cancer surgery in the Department of Thoracic and Cardiac Surgery of Yichang Central People’s Hospital from January 28,2023,to March 3,2023,were selected.They were divided into a pulmonary infection group(47 cases)and a nonpulmonary infection group(45 cases)according to whether pulmonary infection occurred.General clinical data of patients were collected and collated to analyse the related influencing factors of pulmonary infection in lung cancer patients after recovery from COVID-19.Results:Univariate analysis showed that patient age(≥60 years),fever after COVID-19 infection,oral and laryngeal symptoms,digestive tract symptoms,neurological symptoms,long-term smoking history,hypertension history,and operation time(≥3 h)were correlated with pulmonary infection(all P<0.05).There was no significant correlation between postoperative pulmonary infection and sex,ocular,nasal and tongue symptoms,systemic symptoms,duration of COVID-19,COPD,lobectomy site,incision pain,mechanical ventilation time(≥6 h),drainage tube retention time(3 d),surgical method(P>0.05).Logistic multivariate analysis showed that age(≥60 years old),long operation time(≥3 h)and long-term smoking history were independent influencing factors for postoperative pulmonary infection in patients with radical resection of lung cancer(P>0.05).Conclusion:In this study,older age(≥60 years old),long-term smoking history,and long operation time(≥3 h)were risk factors for pulmonary infection after lung cancer surgery.In the future,active treatment measures can be taken to address these risk factors during the perioperative period to reduce the incidence of postoperative pulmonary infection. 展开更多

BACKGROUND:Hospital mortality rates are higher among patients with sepsis-associated acute kidney injury(SA-AKI)than among patients with sepsis.However,the pathogenesis underlying SA-AKI remains unclear.We hypothesized that the source of infection affects development of SA-AKI.We aim to explore the relationship between the anatomical source of infection and outcome in patients with SA-AKI.METHODS:Between January 2013 and January 2018,113 patients with SA-AKI admitted to our Emergency Center were identifi ed and divided into two groups:those with pulmonary infections and those with other sources of infection.For each patient,we collected data from admission until either discharge or death.We also recorded the clinical outcome after 90 days for the discharged patients.RESULTS:The most common source of infection was the lung(52/113 cases,46%),followed by gastrointestinal(GI)(25/113 cases,22.1%)and urinary(22/113,19.5%)sources.Our analysis showed that patients with SA-AKI had a significantly worse outcome(30/52 cases,P<0.001)and poorer kidney recovery(P=0.015)with pulmonary sources of infection than those infected by another source.Data also showed that patients not infected by a pulmonary source more likely experienced shock(28/61 cases,P=0.037).CONCLUSION:This study demonstrated that the source of infection infl uenced the outcome of SA-AKI patients in an independent manner.Lung injury may influence renal function in an asyet undetermined manner as the recovery of kidney function was poorer in SA-AKI patients with a pulmonary source of infection. 展开更多

The intravenous use of nalmefene has been found to exert neuroprotective effect in patients with severe traumatic brain injury and acute cerebral infarction;nonetheless,it is unknown whether nalmefene alleviates delayed neurocognitive recovery.Our purpose of the current research was to clarify the impact of nalmefene on delayed neurocognitive recovery in aged patients experiencing video-assisted thoracic surgery(VATS)with intraoperative use of one lung ventilation(OLV).The present study involved 120 paticents undergoing selective VATS,randomized to accept low-dose nalmefene(N1 group,n=40),high-dose nalmefene(N2 group,1n=40)or equal volume of physiologic saline(control group,1=40).A battery of neuropsychological tests were used to estimate cognitive function I day before surgery(o)and 10 days after surgery or before discharge(t).Regional cerebral oxygen saturation(rSO2)was detected 5 min before induction(t),5 min after induction(1),15 and 60 min after onset of OLV(62 and 13),and 15 min after termination of OLV(4).The plasma values of interleukin(IL)-1β,IL-6,tumor necrosis factor(TNF)-a1 and adiponectin(ADP)were also detected prior to induction of anesthesia(T0),1 h,2 h and 6 h after surgery(TI,T2,T3).On 1,delayed neurocognitive recovery occurred in 5/40(12.5%)patients of NI group,in 5/40(12.5%)patients of N2 group and in 13/40(32.5%)patients of control group(P<0.05).There were no statistical differences in rSO2 among three groups at different time points.At Tl,T2 and T3,IL-1β,IL-6 and TNF-a values significantly increased and ADP value significantly decreased(P<0.05)in control group.In contrast,at TI,T2 and T3,IL-1β,IL-6 and TNF-a values decreased and ADP value decreased less in N1 and N2 groups(P<0.05).At TI,T2 and T3,IL-1β,IL-6 and TNF-a concentrations presented a trend of N2 group<N1 group<control group and ADP presented a trend of N2 group>Nl group>control group(P<0.05).The result of our present research supports the hypothesis that the perioperative intravenous treatment with nalmefene to VATS with OLV ameliorates postoperative cognitive function and decreases the incidence of delayed neurocognitive recovery,most likely by suppression of inflammatory responses. 展开更多

Background:Immunotherapy has become the fastest-adopting treatment paradigm for lung cancer with improved survival.By binding with its ligand(inducible T-cell costimulator and its ligand[ICOSL]),an inducible T-cell co-stimulator(ICOS)could contribute to reversing immunosuppression and improving immune response and thus be a potential target for cancer immunotherapy.Methods:We selected 54 formalin-fixed,paraffin-embedded tumor tissues from cases with stage I–III lung adenocarcinoma cancer.Immunohistochemical expression of ICOS and ICOSL was evaluated.The correlation with clinical parameters in Chinese patients was also compared with TCGA results.Results:The positive rates of ICOS and ICOSL were 68%and 81.5%,respectively,in lung tumor tissues.Of these,9 cases had a low expression of ICOS,and 22 cases had a high expression of ICOS;ICOSL expression was low in 20 cases and high in 24 cases.According to the International Association for the Study of Lung Cancer(8th edition),phase I lesions were detected in 21 cases,phase II lesions in 15 cases,and phase III lesions in 18 cases.The median survival time of all patients was 44.5 months,and the median disease-free survival was 32 months.Univariate analysis showed that the factors significantly associated with overall survival were tumor size,regional lymph node involvement,stage,and expression level of ICOS/ICOSL.Survival analysis using log-rank test indicated that the lower ICOS+cell infiltration may predict poor prognosis,whereas lower ICOSL protein expression may be associated with better prognosis,but ICOSL data need further validation in larger samples due to inconsistency in TCGA mRNA prediction.Conclusion:ICOS/ICOSL might be associated with prognosis of lung cancer,and ICOS and its ligand may be potential therapeutic targets in non-small cell lung cancer. 展开更多

Objective: This study aims to understand the distribution of pathogenic bacteria in the region of HIV/AIDS patients with opportunistic infection. Methods: To count the number of the bacterial culture of HIV/AIDS patients in our hospital from October 2011 to December 2014, and observe the distribution of all kinds of pathogenic bacteria. Results: From the 4269 cases of HIV/AIDS patients’ bacteria, 5045 cases were cultured whose main flora distribution wasCandida albicans, 1759 cases. The second one was penicillium, 982 cases. The third one was mycobacteria, 557 cases. And then there are 213 cases ofCryptococcus neoformans, 212 cases of?Klebsiella pneumonia, 209 cases of?E. coli, 157 cases of coagulase-negative staphylococci, 112 cases of?Candida tropicalis, 90 cases of glabrata, 81 cases of?Staphylococcus aureus, 75 cases of?Pseudomonas aeruginosa, 60 cases of Salmonella, 48 cases of Acinetobacter and the distribution of the rest of cultured bacterial was less than 40 cases. Conclusion: There are many kinds of types of Pathogenic bacteria in HIV/AIDS patients with the opportunity to infectious. And the majorities are?Candida albicans,?Penicillium marneffei,?Penicillium,?Mycobacterium,?Cryptococcus neoformans?and so on. The infection sites are widely distributed;respiratory and circulatory are the main infected system. Improving the detection rate and reducing the contamination rate can truly reflect the distribution of pathogenic bacteria, and the distribution can guide the infection work in hospital. At the same time, it’s good to predict and prevent opportunistic infection. Thus, the patients can get immediate treatment. 展开更多

AIM: To evaluate the safety and efficacy of pegylated interferon alfa-2a and ribavirin therapy in elderly patients with chronic hepatitis C infection.METHODS: Patients characteristics, treatment results and safety profiles of 4859 patients with hepatitis c virus(HCV) infection receiving treatment with pegylatedinterferon alfa-2a and ribavirin were retrieved from a large ongoing German multicentre non-interventional study. Recommended treatment duration was 24 wk for GT 2 and GT 3 infection and 48 wk for GT 1 and GT 4 infection. Patients were stratified according to age(< 60 years vs ≥ 60 years). Because of limited numbers of liver biopsies for further assessment of liver fibrosis APRI(aspartate aminotransferase- platelet ratio index) was performed using pre-treatment laboratory data.RESULTS: Out of 4859 treated HCV patients 301(6.2%) were ≥ 60 years. There were more women(55.8% vs 34.2%, P < 0.001) and predominantly GT 1(81.4% vs 57.3%, P < 0.001) infected patients in the group of patients aged ≥ 60 years and they presented more frequently with metabolic(17.6% vs 4.5%, P < 0.001) and cardiovascular comorbidities(32.6% vs 6.7%, P < 0.001) and significant fibrosis and cirrhosis(F3/4 31.1% vs 14.0%, P = 0.0003). Frequency of dose reduction and treatment discontinuation were significantly higher in elderly patients(30.9% vs 13.7%, P < 0.001 and 47.8% vs 30.8%, P < 0.001). Main reason for treatment discontinuation was "virological non-response"(26.6% vs 13.6%). Sustained virological response(SVR) rates showed an age related difference in patients with genotype 1(23.7% vs 43.7%, P < 0.001) but not in genotype 2/3 infections(57.7% vs 64.6%, P = 0.341). By multivariate analysis, age and stage of liver disease were independent factors of SVR.CONCLUSION: Elderly HCV patients differ in clinical characteristics and treatment outcome from younger patients and demand special attention from their practitioner. 展开更多

They receive treatment in outpatient setting and have a need to self-manage at home. The purpose of this study was to clarify how elderly patients with lung cancer who are undergoing treatment with molecularly targeted drugs in outpatient setting establish self-management. Methods: The study used Kinoshita’s Modified Grounded Theory. Semi-structured interviews were conducted with 17 patients (eight males and nine females). Results: This study identified six categories: Accepting life with cancer, Maintaining activities of daily living without feeling shackled by cancer, Reconsidering how to continue being themselves in daily life until life comes to an end, Using trial and error to integrate treatment and daily living, Formulating their criteria for continuing treatment, and Obtaining help from caregivers. Conclusion: The self-management process in elderly patients consisted of maintaining treatment and integrating treatment with daily living. And they are exploring the effects of treatment and side effects in order to live their own life. Implications for Nursing: In many elderly patients with lung cancer the purpose of treatment is curative extension of survival and improved quality of life. Our findings suggest that is important we help patients to identify how patients want to live, identify ways to improve their quality of life, and share the goals of treatment between the patient and the caregiver. 展开更多

Nephropathy secondary to BK virus, a member of the Papoviridae family of viruses, has been recognized for some time as an important cause of allograft dysfunction in renal transplant recipients. In recent times, BK nephropathy(BKN) of the native kidneys has being increasingly recognized as a cause of chronic kidney disease in patients with solid organ transplants, bone marrow transplants and in patients with other clinical entities associated with immunosuppression. In such patients renal dysfunction is often attributed to other factors including nephrotoxicity of medications used to prevent rejection of the transplanted organs. Renal biopsy is required for the diagnosis of BKN. Quantitation of the BK viral load in blood and urine are surrogate diagnostic methods. The treatment of BKN is based on reduction of the immunosuppressive medications. Several compounds have shown antiviral activity, but have not consistently shown to have beneficial effects in BKN. In addition to BKN, BK viral infection can cause severe urinary bladder cystitis, ureteritis and urinary tract obstruction as well as manifestations in other organ systems including the central nervous system, the respiratory system, the gastrointestinal system and the hematopoietic system. BK viral infection has also been implicated in tumorigenesis. The spectrum of clinical manifestations from BK infection and infection from other members of the Papoviridae family is widening. Prevention and treatment of BK infection and infections from other Papovaviruses are subjects of intense research. 展开更多

This study is designed to develop Artificial Intelligence(AI)based analysis tool that could accurately detect COVID-19 lung infections based on portable chest x-rays(CXRs).The frontline physicians and radiologists suffer from grand challenges for COVID-19 pandemic due to the suboptimal image quality and the large volume of CXRs.In this study,AI-based analysis tools were developed that can precisely classify COVID-19 lung infection.Publicly available datasets of COVID-19(N=1525),non-COVID-19 normal(N=1525),viral pneumonia(N=1342)and bacterial pneumonia(N=2521)from the Italian Society of Medical and Interventional Radiology(SIRM),Radiopaedia,The Cancer Imaging Archive(TCIA)and Kaggle repositories were taken.A multi-approach utilizing deep learning ResNet101 with and without hyperparameters optimization was employed.Additionally,the fea-tures extracted from the average pooling layer of ResNet101 were used as input to machine learning(ML)algorithms,which twice trained the learning algorithms.The ResNet101 with optimized parameters yielded improved performance to default parameters.The extracted features from ResNet101 are fed to the k-nearest neighbor(KNN)and support vector machine(SVM)yielded the highest 3-class classification performance of 99.86%and 99.46%,respectively.The results indicate that the proposed approach can be bet-ter utilized for improving the accuracy and diagnostic efficiency of CXRs.The proposed deep learning model has the potential to improve further the efficiency of the healthcare systems for proper diagnosis and prognosis of COVID-19 lung infection. 展开更多

According to the WHO the incidence of ISO varies from 0.5% to 15% and exceeds 25% in developing countries. They result from the combined action of several factors and represent a concern for public health. To study the contributing factors of surgical site infections in patients operated at the University Clinic of Orthopedic Traumatology of CNHU-HKM of Cotonou. Method: This was an analytical cross-sectional study that involved 35 operated patients and ten nurses. Were included in our study: 1) All patients, without distinction of sex or age, having been operated on in the university clinic of orthopedic traumatology, during the survey period;2) Patients hospitalized for post-operative care during the survey period;3) The nursing staff on duty during our study period. The usual statistical measures were used according to the type of variables: means, standard deviations, percentages. Data analysis first involved calculating percentages for the qualitative variables and means followed by their standard deviations for the quantitative variables. Next, the Pearson Chi-square test was used to test the association between the dependent variable and the independent variables of interest. The significance level is set at p Results: The prevalence of surgical site infections was 28.58%. The main factors contributing to the occurrence of SSIs that were found were the patient’s level of education (p = 0.003) and the reuse of bandages used for dressing (p = 0.004). Other potential factors such as the economic status of the patient, the poor quality of technical dressings, and the preoperative stay were also highlighted. Conclusion: Surgical site infections remain a global concern. Risk factors were found on both the patient and nurse sides. It is urgent to address these various factors to minimize the occurrence of surgical site infections. 展开更多

BACKGROUND Nocardia pneumonia shares similar imaging and clinical features with pulmonary tuberculosis and lung neoplasms,but the treatment and anti-infective medication are completely different.Here,we report a case of pulmonary nocardiosis caused by Nocardia cyriacigeorgica(N.cyriacigeorgica),which was misdiagnosed as community-acquired pneumonia(CAP)with repeated fever.CASE SUMMARY A 55-year-old female was diagnosed with community-acquired pneumonia in the local hospital because of repeated fever and chest pain for two months.After the anti-infection treatment failed in the local hospital,the patient came to our hospital for further treatment.Enhanced computed tomography showed multiple patchy,nodular and strip-shaped high-density shadows in both lungs.A routine haematological examination was performed and showed abnormalities in CD19+B cells and CD4+T cells.Positive acid-fast bifurcating filaments and branching gram-positive rods were observed in the bronchoalveolar lavage fluid of the patient under an oil microscope,which was identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry as N.cyriacigeorgica.The patient’s condition quickly improved after taking 0.96 g compound sulfamethoxazole tablets three times a day.CONCLUSION The antibiotic treatment of Nocardia pneumonia is different from that of common CAP.Attention should be given to the pathogenic examination results of patients with recurrent fever.Nocardia pneumonia is an opportunistic infection.Patients with CD4+T-cell deficiency should be aware of Nocardia infection. 展开更多

BACKGROUND Chronic obstructive pulmonary disease(COPD)is a common respiratory disorder that affects the elderly population and increases the risk of postoperative pulmonary complications(PPCs)after major surgeries.Sevoflurane is a volatile anesthetic that has been shown to have anti-inflammatory and antioxidant properties and attenuate lung injury in animal models.AIM To evaluate the protective effect of sevoflurane on the lung function of elderly COPD patients undergoing total hip arthroplasty(THA).METHODS In this randomized controlled trial,we randomly assigned 120 elderly patients with COPD,who were scheduled for THA,to receive either sevoflurane(sevoflurane group)or propofol(propofol group)as the maintenance anesthetic.The primary outcome was the incidence of PPCs within seven days after surgery.The secondary outcomes were changes in the lung function parameters,inflammatory markers,oxidative stress markers,and postoperative pain scores.RESULTS The results showed that the incidence of PPCs was significantly lower in the sevoflurane group than in the propofol group(10%vs 25%,P=0.02).Furthermore,the decline in the forced expiratory volume in 1 s,forced vital capacity,and peak expiratory flow was significantly lesser in the sevoflurane group than in the propofol group at 24 h and 48 h after surgery(P<0.05).The interleukin-6,tumor necrosis factor-alpha,malondialdehyde,and 8-hydroxy-2α-deoxyguanosine levels were significantly lower in the sevoflurane group than in the propofol group at 24 h after surgery(P<0.05).The sevoflurane group showed significantly lower postoperative pain scores than the propofol group at 6 h,12 h,and 24 h after surgery(P<0.05).CONCLUSION Sevoflurane protects the lung function of elderly COPD patients undergoing THA under general anesthesia by reducing the incidence of PPCs,attenuating inflammatory and oxidative stress responses,and alleviating postoperative pain. 展开更多

Infection may occur through inhalation of spores or via direct inoculation into the skin. Typically there is a history of immunosuppression, but cases are also reported in immunocompetent hosts. Cryptococcus may manifest as pulmonary disease or primary cutaneous infection, but dissemination to a systemic illness is the most life-threatening concern. We present the case of a 71-year-old man with a four-year history of idiopathic lung disease, treated with oral prednisone and mycophenolate, presents with a new onset skin rash on the right wrist. He has a history of cleaning and clearing barns and sheds after a recent storm devastated the area. Birds and bats were present in these structures while he was working. Initial therapy failed, and subsequent biopsy showed the presence of Cryptococcus yeast. Further investigation yielded a positive, low titer Cryptococcus antigen screen but negative blood cultures. This case illustrates three valuable facets of patient care. Ideally, one diagnosis will explain all of the clinical presentation, but when that is not the case then multiple etiologies must be explored. Sometimes first-line therapy is ineffective, and the clinician should not be afraid to recognize that and change course. Importantly with skin lesions, failure to respond to treatment or worsening of the lesion in the face of topical and/or oral steroids should lead one to consider the possibility of infection, particularly in an immunosuppressed patient, and prompt biopsy is prudent. 展开更多

Purpose of the Research: Our study aimed to determine and understand the risk factors of surgical site infections in patients operated on in general surgery wards. Method of Research: Between May 2008 and November 2008, 422 consecutive patients who underwent emergency and elective surgeries, excluding breast, goitre and laparoscopic surgeries, were included in the study to determine surgical site infections and risk factors. The patients’ risk factors were selected in the preoperative period, and postoperative 3<sup>rd</sup>, 7<sup>th</sup>, and 30<sup>th</sup> days were checked by the physician responsible for conducting the study regarding surgical site infection. Results and Conclusion: Surgical site infections were defined as incisional and organ/space based on NNIS data. Gender, diabetes mellitus, malignancy, degree of contamination, ASA score ≥ 3, preoperative skin cleansing, duration of intensive care unit stay, duration of hospital stay, growth in wound culture, duration of surgery and incision length were determined as risk factors increasing CAI rates. Especially the degree of contamination, duration of intensive care unit stay, hospitalisation, duration of operation, and growth in wound culture were decisive factors in the development of CAI. As a result of our study, in the light of these data, we concluded that to prevent the development of CAI can be modified, interventions to foreseeable factors can be assessed. 展开更多

AIM: To assess H pylori seroprevalence in lung cancer and determine whether there is a potential association between lung cancer and H pylori infection. METHODS: The study was conducted on forty consecutive patients with lung cancer, confirmed by pathology (32 men, 8 women; mean age 55.50 ± 11.91 years, range 16-77 years). Forty healthy subjects (25 men, 15 women; mean age 43.08 ± 12.60 years, range 20-79 years) from the patients’ family members were matched to each case subject on the basis of age and socioeconomic status. H pylori infection was detected with a commercially available immunoglobulin G (IgG) enzyme-linked immunosorbent assay (Trinity kit, Biotech co., USA), previously validated in adults (86% sensitivity, 96% specificity) against a gold standard of culture and histology. RESULTS: H pylori seropositivity was present in 52.5% of patients with lung cancer in comparison to 45.0% of healthy control subjects. Although H pylori seropositivity was more frequent in lung cancer patients than in controls, the difference did not reach statistical significance (OR = 1.35, 95% CI = 0.56-3.25; P = 0.65). In addition, there was no significant difference between cases and controls in terms of gastrointestinal symptoms. CONCLUSION: The earlier described association between H pylori infection and lung cancer was not supported in this study. Further studies with larger sample sizes should be undertaken to assess the frequency of H pylori infection in patients with lung cancer and their potential association. 展开更多
