Anxiety and depression among patients with non-tuberculous mycobacterial disease in Shanghai: a cross-sectional study

ObjectiveTo understand the mental health status and its influencing factors among patients with non-tuberculous mycobacterial disease and to provide a reference for medical staff to formulate scientific and feasible intervention strategies.MethodsA total of 114 patients diagnosed with non-tuberculous mycobacillosis during hospitalization in the Department of Infection from September 2020 to April 2021 were selected as the research participants. Participants’ mental health status and related factors were evaluated using a self-made general patient information questionnaire, self-rating Anxiety Scale (SAS), and self-rating Depression Scale (SDS).ResultsAmong 114 patients with non-tuberculous mycosis, 61 (53.51%) exhibited depressive symptoms, and the SDS score was 51.15 ± 13.04, which was higher than the national norm of 41.88 ± 10.57 (p < 0.05); further, 39 patients (34.21%) showed anxiety symptoms, and the SAS score was 45.75 ± 10.81, which was significantly higher than the national norm of 29.78 ± 10.07 (p < 0.05). Body mass index and monthly household income had significant effects on depression in patients with non-tuberculous mycobacterial disease (p < 0.05). Educational level had a significant effect on the anxiety state of patients with non-tuberculous mycobacterial disease (p < 0.05).ConclusionPatients with non-tuberculous mycobacterial disease are prone to depression and anxiety. Nurses should pay attention to it in clinical work for the timely identification of and intervention for anxiety and depression and intervene

Lab-in-a-Tube: A portable imaging spectrophotometer for cost-effective, high-throughput, and label-free analysis of centrifugation processes

Centrifuges serve as essential instruments in modern experimental sciences, facilitating a wide range of routine sample processing tasks that necessitate material sedimentation. However, the study for real time observation of the dynamical process during centrifugation has remained elusive. In this study, we developed an innovative Lab_in_a_Tube imaging spectrophotometer that incorporates capabilities of real time image analysis and programmable interruption. This portable LIAT device costs less than 30 US dollars. Based on our knowledge, it is the first Wi Fi camera built_in in common lab centrifuges with active closed_loop control. We tested our LIAT imaging spectrophotometer with solute solvent interaction investigation obtained from lab centrifuges with quantitative data plotting in a real time manner. Single re circulating flow was real time observed, forming the ring shaped pattern during centrifugation. To the best of our knowledge, this is the very first observation of similar phenomena. We developed theoretical simulations for the single particle in a rotating reference frame, which correlated well with experimental results. We also demonstrated the first demonstration to visualize the blood sedimentation process in clinical lab centrifuges. This remarkable cost effectiveness opens up exciting opportunities for centrifugation microbiology research and paves the way for the creation of a network of computational imaging spectrometers at an affordable price for large scale and continuous monitoring of centrifugal processes in general.Comment: 21 Pages, 6 Figure

Broadband nonlinear modulation of incoherent light using a transparent optoelectronic neuron array

Nonlinear optical processing of ambient natural light is highly desired in computational imaging and sensing applications. A strong optical nonlinear response that can work under weak broadband incoherent light is essential for this purpose. Here we introduce an optoelectronic nonlinear filter array that can address this emerging need. By merging 2D transparent phototransistors (TPTs) with liquid crystal (LC) modulators, we create an optoelectronic neuron array that allows self-amplitude modulation of spatially incoherent light, achieving a large nonlinear contrast over a broad spectrum at orders-of-magnitude lower intensity than what is achievable in most optical nonlinear materials. For a proof-of-concept demonstration, we fabricated a 10,000-pixel array of optoelectronic neurons, each serving as a nonlinear filter, and experimentally demonstrated an intelligent imaging system that uses the nonlinear response to instantly reduce input glares while retaining the weaker-intensity objects within the field of view of a cellphone camera. This intelligent glare-reduction capability is important for various imaging applications, including autonomous driving, machine vision, and security cameras. Beyond imaging and sensing, this optoelectronic neuron array, with its rapid nonlinear modulation for processing incoherent broadband light, might also find applications in optical computing, where nonlinear activation functions that can work under ambient light conditions are highly sought.Comment: 20 Pages, 5 Figure

International Nosocomial Infection Control Consortium (INICC) report, data summary for 2003-2008, issued June 2009

Q3Artículo original95-106We report the results of the International Infection Control Consortium (INICC) surveillance study from January 2003 throughDecember 2008 in 173 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study, using Centersfor Disease Control and Prevention (CDC) US National Healthcare Safety Network (NHSN; formerly the National Nosocomial Infec-tion Surveillance system [NNIS]) definitions for device-associated health care-associated infection, we collected prospective datafrom 155,358 patients hospitalized in the consortium’s hospital ICUs for an aggregate of 923,624 days. Although device utilizationin the developing countries’ ICUs was remarkably similar to that reported from US ICUs in the CDC’s NHSN, rates of device-asso-ciated nosocomial infection were markedly higher in the ICUs of the INICC hospitals: the pooled rate of central venous catheter(CVC)-associated bloodstream infections (BSI) in the INICC ICUs, 7.6 per 1000 CVC-days, is nearly 3-fold higher than the 2.0 per1000 CVC-days reported from comparable US ICUs, and the overall rate of ventilator-associated pneumonia (VAP) was also farhigher, 13.6 versus 3.3 per 1000 ventilator-days, respectively, as was the rate of catheter-associated urinary tract infection (CAUTI),6.3 versus 3.3 per 1000 catheter-days, respectively. Most strikingly, the frequencies of resistance ofStaphylococcus aureusisolatesto methicillin (MRSA) (84.1% vs 56.8%, respectively),Klebsiella pneumoniaeto ceftazidime or ceftriaxone (76.1% vs 27.1%, respec-tively),Acinetobacter baumanniito imipenem (46.3% vs 29.2%, respectively), andPseudomonas aeruginosato piperacillin (78.0%vs 20.2%, respectively) were also far higher in the consortium’s ICUs, and the crude unadjusted excess mortalities of device-relatedinfections ranged from 23.6% (CVC-associated bloodstream infections) to 29.3% (VAP)

International Nosocomial Infection Control Consortium (INICC) report, data summary of 36 countries, for 2004-2009

The results of a surveillance study conducted by the International Nosocomial Infection Control Consortium (INICC) from January 2004 through December 2009 in 422 intensive care units (ICUs) of 36 countries in Latin America, Asia, Africa, and Europe are reported. During the 6-year study period, using Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN; formerly the National Nosocomial Infection Surveillance system [NNIS]) definitions for device-associated health care-associated infections, we gathered prospective data from 313,008 patients hospitalized in the consortium's ICUs for an aggregate of 2,194,897 ICU bed-days. Despite the fact that the use of devices in the developing countries' ICUs was remarkably similar to that reported in US ICUs in the CDC's NHSN, rates of device-associated nosocomial infection were significantly higher in the ICUs of the INICC hospitals; the pooled rate of central line-associated bloodstream infection in the INICC ICUs of 6.8 per 1,000 central line-days was more than 3-fold higher than the 2.0 per 1,000 central line-days reported in comparable US ICUs. The overall rate of ventilator-associated pneumonia also was far higher (15.8 vs 3.3 per 1,000 ventilator-days), as was the rate of catheter-associated urinary tract infection (6.3 vs. 3.3 per 1,000 catheter-days). Notably, the frequencies of resistance of Pseudomonas aeruginosa isolates to imipenem (47.2% vs 23.0%), Klebsiella pneumoniae isolates to ceftazidime (76.3% vs 27.1%), Escherichia coli isolates to ceftazidime (66.7% vs 8.1%), Staphylococcus aureus isolates to methicillin (84.4% vs 56.8%), were also higher in the consortium's ICUs, and the crude unadjusted excess mortalities of device-related infections ranged from 7.3% (for catheter-associated urinary tract infection) to 15.2% (for ventilator-associated pneumonia).

International Nosocomial Infection Control Consortium report, datasummary of 50 countries for 2010-2015 : Device-associated module

Q3Artículo original1495-1504Background: We report the results of International Nosocomial Infection Control Consortium (INICC) sur-veillance study from January 2010-December 2015 in 703 intensive care units (ICUs) in Latin America,Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific.Methods:During the 6-year study period, using Centers for Disease Control and Prevention National Health-care Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 861,284 patients hospitalized in INICC hospital ICUs for an aggregateof 3,506,562 days.Results:Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAIrates were higher in the INICC ICUs: in the INICC medical-surgical ICUs, the pooled rate of central line-associated bloodstream infection, 4.1 per 1,000 central line-days, was nearly 5-fold higher than the 0.8per 1,000 central line-days reported from comparable US ICUs, the overall rate of ventilator-associatedpneumonia was also higher, 13.1 versus 0.9 per 1,000 ventilator-days, as was the rate of catheter-associated urinary tract infection, 5.07 versus 1.7 per 1,000 catheter-days. From blood cultures samples,frequencies of resistance ofPseudomonasisolates to amikacin (29.87% vs 10%) and to imipenem (44.3%vs 26.1%), and ofKlebsiella pneumoniaeisolates to ceftazidime (73.2% vs 28.8%) and to imipenem (43.27%vs 12.8%) were also higher in the INICC ICUs compared with CDC-NHSN ICUs.Conclusions:Although DA-HAIs in INICC ICU patients continue to be higher than the rates reported inCDC-NSHN ICUs representing the developed world, we have observed a significant trend toward the re-duction of DA-HAI rates in INICC ICUs as shown in each international report. It is INICC’s main goal tocontinue facilitating education, training, and basic and cost-effective tools and resources, such as stan-dardized forms and an online platform, to tackle this problem effectively and systematically

Device-associated infection rates in 398 intensive care units in Shanghai, China: International Nosocomial Infection Control Consortium (INICC) findings

Objectives: To determine device-associated healthcare-associated infection (DA-HAI) rates and the microorganism profile in 398 intensive care units (ICUs) of 70 hospitals in Shanghai, China. Methods: An open-label, prospective, cohort, active DA-HAI surveillance study was conducted on patients admitted to 398 tertiary-care ICUs in China from September 2004 to December 2009, implementing the methodology developed by the International Nosocomial Infection Control Consortium (INICC). The data were collected in the participating ICUs, and uploaded and analyzed at the INICC headquarters on proprietary software. DA-HAI rates were registered by applying the definitions of the US Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN). We analyzed the rates of DAI-HAI, ventilator-associated pneumonia (VAP), central line-associated bloodstream infection (CLABSI), and catheter-associated urinary tract infection (CAUTI), and their microorganism profiles. Results: During the 5 years and 4 months of the study, 391 527 patients hospitalized in an ICU for an aggregate of 3 245 244 days, acquired 20 866 DA-HAIs, an overall rate of 5.3% (95% confidence interval (CI) 5.3-5.4) and 6.4 (95% CI 6.3-6.5) infections per 1000 ICU-days. VAP posed the greatest risk (20.8 per 1000 ventilator-days, 95% CI 20.4-21.1), followed by CAUTI (6.4 per 1000 catheter-days, 95% CI 6.3-6.6) and CLABSI (3.1 per 1000 catheter-days, 95% CI 3.0-3.2). The most common isolated microorganism was Acinetobacter baumannii (19.1%), followed by Pseudomonas aeruginosa (17.2%), Klebsiella pneumoniae (11.9%), and Staphylococcus aureus (11.9%). Conclusions: DA-HAIs in the ICUs of Shanghai pose a far greater threat to patient safety than in ICUs in the USA. This is particularly the case for the VAP rate, which is much higher than the rates found in developed countries. Active infection control programs that carry out infection surveillance and implement prevention guidelines can improve patient safety and must become a priority.

Association between the overall burden of comorbidity and Ct values among the older patients with Omicron infection: Mediated by inflammation

ObjectivesTo investigate the associations between the overall burden of comorbidity, inflammatory indicators in plasma and Ct values among the elderly with COVID-19.MethodsWe conducted a retrospective observational study. The results of each nucleic acid test of during hospitalization were obtained. Linear regression models assessed the associations between the overall burden of comorbidity, inflammatory indicators in plasma and Ct values among the elderly. A causal mediation analysis was performed to assess the mediation effects of inflammatory indicators on the association between the overall burden of comorbidity and Ct values.ResultsA total of 767 COVID-19 patients aged ≥ 60 years were included between April 2022 and May 2022. Patients with a high burden of comorbidity had significantly lower Ct values of the ORF gene than subjects with a low burden of comorbidity (median, 24.81 VS 26.58, P < 0.05). Linear regression models showed that a high burden of comorbidity was significantly associated with higher inflammatory responses, including white blood cell count, neutrophil count and C-reactive protein. Also, white blood cell count, neutrophil count, C-reactive protein and the overall burden of comorbidity assessed by age-adjusted Charlson comorbidity index were independent risk factors for the Ct values. A mediation analysis detected the mediation effect of white blood cells on the association between the burden of comorbidity and Ct values, with the indirect effect estimates of 0.381 (95% CI: 0.166, 0.632, P < 0.001). Similarly, the indirect effect of C-reactive protein was -0.307 (95% CI: -0.645, -0.064, P = 0.034). White blood cells and C-reactive protein significantly mediated the relationship between the burden of comorbidity and Ct values by 29.56% and 18.13% of the total effect size, respectively.ConclusionsInflammation mediated the association between the overall burden of comorbidity and Ct values among elderly with COVID-19, which suggests that combined immunomodulatory therapies could reduce the Ct values for such patients with a high burden of comorbidity

Prolonged Use of Surgical Masks and Respirators Affects the Protection and Comfort for Healthcare Workers

This study explored the ideal period for wearing masks to prevent the physiological and psychological problems associated with long-term face mask use during respiratory infections by healthcare workers. Breathing simulators, surgical masks (SM) and medical respirators (PM) were prepared for two to eight hours. Changes in the comfort of masks (facial skin temperature, breathing resistance, and moisture permeability) and protection (filtration efficiency, resistance to blood penetration, and colony count) were assessed. The results demonstrated that the masks offered efficient liquid-particle filtering even after eight hours of use. However, the number of bacterial colonies using PM and SM grew significantly after two and four hours, respectively. Concerning comfort, the inspiratory resistance of masks rose dramatically after two hours, whereas the moisture permeability declined considerably after four hours. In addition, skin temperature had a significant increase within two hours, which may result in facial discomfort. When conditions permitted, the hospital staff was instructed to replace their masks every two hours
