RESUMO
With the rising aging population, the number of people with stroke, dementia and Parkinson's disease is huge.These patients often have swallowing dysfunction, cognitive decline, decreased immune function, long-term bed rest, malnutrition, and sarcopenia, and are prone to pneumonia.However, the clinical manifestations of these patients with pneumonia are non-specific.The patients often cannot accurately express their complaints, resulting in symptoms being ignored.The underlying diseases of the nervous system increase the risk of pneumonia-related death, and is associated with poor prognosis.This article aimed to review the risk factors, prevention and treatment of these three neurological disorders complicated with pneumonia.
RESUMO
Community acquired pneumonia(CAP)is characterized by high morbidity and mortality in immunocompromised patients, with the elderly as the main vulnerable population.However, current guidelines in China and elsewhere do not offer specific recommendations on the diagnosis and treatment of such patients.This paper reviews the definition, classification, epidemiology, etiological characteristics, clinical manifestations, diagnosis, treatment and prognosis of CAP in immunocompromised elderly patients, to provide a theoretical framework for its diagnosis and treatment and for the formulation of guidelines.
RESUMO
Aspiration is the entry of oropharyngeal or gastric contents into the lower respiratory tract through the glottis, a common and important cause of death in elderly patients due to lung infections.However, a lack of accurate and rapid clinical methods for the diagnosis of aspiration leads to misdiagnosis, missed diagnosis or delayed diagnosis of aspiration, especially aspiration pneumonia.In recent years, with further research into the mechanisms of aspiration syndromes, multiple aspiration biomarkers with potential and clinical translational value have been found, and may help early detection of aspiration and have important and practical significance for elderly health.Therefore, this article reviews aspiration biomarkers such as pepsin, α-amylase, bile acid and other potential biomarkers as well as current relevant research, detection methods, their clinical value and prospects concerning challenges and directions of innovation in future research.
RESUMO
Objective:To investigate the clinical and mycological characteristics, treatment and prognosis of invasive candidiasis(IC)in the elderly.Methods:This retrospective study included aged patients(≥65 years)admitted to the Peking University First Hospital between January, 2010 and December, 2019, who were diagnosed with IC based on positive culture results.The infecting strains were re-identified and their antifungal drug resistance was tested.The clinical and mycological characteristics, treatment and prognosis information of the elderly patients were collected and compared with those of non-elderly adults.Results:A total of 99 aged patients were included, with a median age of 78(70-83)years and a male-to-female ratio of 2.1∶1.0.The elderly accounted for 62.7%(99/158)of the adult IC patients.Compared with their younger counterparts, elderly patients were more likely to need medium-to long-term hospitalization and intensive care unit(ICU)stay, and to show concurrent heart failure, respiratory failure or renal failure, to require mechanical ventilation, and to show deep-seated bacterial infections and multifocal Candida colonization, especially for those with previous fluconazole exposure( P<0.05). Bloodstream was the most common Candida transmission route(71/99, 71.7%)and Candida albicans was the most prevalent species(47/99, 47.5%). Antifungal resistance was highest for fluconazole(17/117, 14.5%)and voriconazole(15/117, 12.8%). No significant difference was found between elderly patients and non-elderly patients in terms of infected sites, Candida species, and antifungal resistance( P>0.05). A total of 86 patients(86.9%)received systemic antifungal treatment and fluconazole was the most commonly used drug(35/86, 40.7%). The thirty-day all-cause mortality in aged IC patients was 32.6%(29/89), significantly higher than in younger patients( P=0.022). Logistic regression analysis revealed that advanced age( OR=1.12, 95% CI: 1.06-1.20, P<0.001), renal failure( OR=4.81; 95% CI: 1.65-14.03; P=0.004), and a high Candida score( OR=1.81, 95% CI: 1.06-3.11, P=0.031)significantly increased the risk of death. Conclusions:Elderly patients were the main affected population of IC, and the mortality of IC steadily increases with age.Treatment for aged IC patients should be proactive and cautious.
RESUMO
The population is susceptible to Coronavirus disease 2019(COVID-19), and the proportion of severe cases and fatality rate in the elderly are higher.For patients with COVID-19, clinicians routinely monitor their inflammatory markers, such as neutrophils, lymphocytes, C-reactive protein, procalcitonin, interleukin-6, serum amyloid A, tumor necrosis factor-α, serum albumin, interleukin-3 and others.This article reviews the diagnostic value of the above mentioned inflammatory markers for COVID-19 in the elderly.It aims to provide a reference for the clinical diagnosis and management of these patients.
RESUMO
Coronavirus disease 2019 (COVID-19) can cause great damage to the elderly patients and lead to high mortality. The clinical presentations and auxiliary examinations of the elderly patients with COVID-19 are atypical, due to the physiological ageing deterioration and basal pathological state. The treatment strategy for the elderly patients has its own characteristics and treatment protocol should be considered accordingly. To improve the diagnosis, treatment, and prevention of COVID-19 in the elderly, the Expert Committee of Geriatric Respiratory and Critical Care Medicine, China Society of Geriatrics established the "Expert consensus for the diagnosis, treatment, and prevention of coronavirus disease 2019 in the elderly" . We focused on the clinical characteristics and key points for better treatment and prevention of COVID-19 in the elderly. (1) For diagnosis, atypical clinical presentation of COVID-19 in the elderly should be emphasized, which may be complicated by underlying disease. (2) For treatment, strategy of multiple disciplinary team (mainly the respiratory and critical care medicine) should be adopted and multiple systemic functions should be considered. (3) For prevention, health care model about integrated management of acute and chronic diseases, in and out of hospital should be applied.
RESUMO
By introducing the unqualified cases of radiation emission test of medical laser equipment, this paper analyses the causes of the problems and the corrective measures adopted, and analyses the effectiveness of the corrective measures. It is proposed that the design rules and rules related to radiation emission should be mastered from the input stage of product design and development, and the radiation emission problem should be considered and solved as soon as possible.

Primary lesions unknown metastatic cancer ( CUP) is a class of histopathologically confirmed metastases. However,a variety of clinical diagnosis and treatment can not clear the primary tumor. The identifica-tion of tumor primary site is the first step in the diagnosis of CUP. The histopathology,immunohistochemistry and PET /CT are commonly used clinical diagnosis and treatment. Gene expression profiling technique is a new meth-od for the diagnosis of primary tumor in recent years. It has high diagnostic accuracy,sensitivity and specificity, and is expected to achieve individual treatment of patients with CUP.
