Healthcare-associated infections are common adverse events in healthcare settings, causing significant morbidity and mortality. There has been a significant increase in the commitment to Infection Prevention and Control worldwide in recent years. This important role and responsibilities are relying on the infection prevention and control practitioners (IPCPs). The competencies of IPCP is thus critical to the success of infection surveillance, prevention, and control program. IPCPs must ensure that they are competent in addressing the challenges they face and are equipped to be competent in fulfilling their duties. Core competencies and professional development of IPCP differ among countries while some are more progressive than the others. This review is aiming to be a reference to develop IPCP core competencies framework and professional development conducive for Asia Pacific region.
Patients undergoing coronary artery bypass grafting (CABG) belong to the very high-risk group of atherosclerotic cardiovascular disease. Although CABG gets advantages in relieving symptoms and improving long-term outcomes, a significant risk of cardiovascular adverse events after surgery still exists and standardized secondary prevention is needed. Lipid management plays a critical role as a secondary preventive strategy in CABG. However, lipid management of CABG patients in real clinical setting is inadequate, including lack of standardized lipid-lowering strategy, low goal attainment rate, as well as poor long-term medication adherence. In recent years, a series of clinical trials have provided a lot of groundbreaking new evidence for lipid management in patients with cardiovascular diseases which offers new strategies together with objectives of lipid-lowering and comprehensive management for patients undergoing CABG. This article reviews the strategy and research progress of lipid management after CABG, aiming to provide objective reference for clinical treatment.
Objective To summarize the related risk factors and preventive measures of acute pancreatitis (AP) combined with portal vein system thrombosis (PVST). Method The literatures on the general clinical characteristics, pathogenesis, risk factors and prevention prognosis of AP with PVST in recent years at home and abroad were reviewed. Results The incidence of AP combined with PVST was increasing, and the pathogenesis was complex, primarily related to pancreatitis and direct venous compression, which caused blood flow stagnation and hemodynamic disturbance, followed by induced venous thrombosis. Pancreatic necrosis, peripancreatic fluid volume accumulation and the severity of pancreatitis were the main risk factors for the onset of pancreatitis. Other local and systemic factors such as coagulation dysfunction, malnutrition, esophageal and gastric varices had also been reported in the literatures. At present, the prevention methods reported in relevant studies include anticoagulation treatment, pancreatic surgery debridement and drainage, nutritional support, systemic and local inflammation intervention, and early fluid resuscitation, etc. Conclusions The risk factors and pathogenesis of AP combined with PVST are complex and diverse, which requires early identification by clinical workers, early intervention and treatment to avoid or reduce the occurrence of PVST as much as possible to improve the prognosis of patients. However, some preventive measures still need further research to verify their safety and effectiveness.
ObjectiveTo develop a standardized venous thromboembolism (VTE) prevention program for burn patients and verify its safety and effectiveness by comparing with traditional thrombus prophylaxis.MethodsAll burn patients admitted and met selection criteria betweem April 2017 and September 2018 were included. Patients between January 2018 and September 2018 were included as the interventional group to implement standardized VTE prevention programs, while patients between April 2017 and December 2017 were included as the control group and traditional active and passive exercises were used to prevent VTE. There was no significant difference in the age, gender, ethnic group, marriage, education, occupation, type and site of the injury, burn area, operation time, and hospital stay between the two groups (P>0.05), which was comparable. The incidence of VTE, number of cases of tissue or organ hemorrhage, survival rate of skin grafting, and time of wound healing were compared.ResultsThe incidence of VTE was obviously lower in the interventional group (1.56%, 1/64) than in the control group (10.17%, 6/59) (χ2=?2.05, P=0.04). No bleeding occurred in any tissue or organ in the two groups. The survival rate of skin grafting and the time of wound healing were 89.06% (57/64) and (11.78±3.08) days respectively in the interventional group and 91.53% (54/59) and (11.66±2.30) days respectively in the control group; and the differences between the two groups were not statistically significant (χ2=0.21, P=0.65; t=?0.22, P=0.83).ConclusionThe standardized VTE prevention program can effectively prevent the occurrence of VTE, and its safety is relatively high.
The epidemiology of respiratory viruses in China are complex and diverse, and viral infections are prone to secondary mucormycosis, posing serious challenges to clinical and public health. The consensu is formulated by domestic experts organized by the Center of Infectious Diseases of West China Hospital of Sichuan University, aiming to identify high-risk groups of respiratory virus infection secondary to mucormycosis, and put forward systematic prevention suggestions. The content covers four aspects: education and training, personal protection, early diagnosis and treatment, and infection control, forming 11 specific recommended measures. It also points out the prevention measures that are still controversial or lack evidence and future research directions, in order to improve the understanding of clinical medical staff, optimize prevention and control strategies, and reduce the risk of secondary mucormycosis.
ObjectiveTo summarize the prevention and treatment of iatrogenic medial collateral ligament (MCL) injuries in total knee arthroplasty (TKA).MethodsThe relevant literature about iatrogenic MCL injuries in TKA was summarized, and the symptoms, causes, preventions, and treatments were analyzed.ResultsPreventions on the iatrogenic MCL injuries in TKA is significantly promoted. With the occurrence of MCL injuries, the femoral avulsion can be fixed with the screw and washer or the suture anchors; the tibial avulsion can be treated with the suture anchors fixation, bone staples fixation, or conservative treatment; the mid-substance laceration can be repaired directly; the autologous quadriceps tendon, semitendinosus tendon, or artificial ligament can be used for the patients with poor tissue conditions or obvious residual gap between the ligament ends; the use of implant with greater constraint can be the last alternative method.ConclusionNo consensus has been reached to the management of iatrogenic MCL injuries in TKA. Different solutions and strategies can be integrated and adopted flexibly by surgeons according to the specific situation.
Objective To discuss the epidemiological characteristics of young and middle-aged people infected with COVID-19 in Gansu province under the new epidemic policy. Methods A total of 1800 people were collected from two tertiary hospitals in Gansu province from November 8, 2022 to January 28, 2023. The vaccination status, nucleic acid antigen detection, the specific time of infection, main symptoms and severity of the disease were investigated. Results Among 1800 participants, 1685 (93.6%) were vaccinated and 1565 (86.9%) were infected with COVID-19. Among the 1565 infected persons, 523 (33.4%) completed both nucleic acid and antigen testing, 382 (24.4%) completed nucleic acid testing, 490 (31.3%) completed antigen testing, 170 (10.9%) received IgG testing. 1490 (95.2%) were slight ill, 75 (4.8%) were critical ill, and 96 (6.1%) were hospitalized, and no one died. In 2022, 92 cases (5.9%) were infected in the first half of November, 141 cases (9.1%) in the second half of November, 630 cases (40.3%) in the first half of December, and 553 cases (35.4%) in the second half of December. 109 cases (7.0%) were infected in the first half of January, 38 cases (2.2%) in the second half of January, and 2 cases (0.1%) in the first half of February of 2023. and no cases in the second half of February. Among the 1565 infected persons, 825 (52.7%) had respiratory symptoms, 293 (18.7%) had gastrointestinal symptoms, 257 (16.4%) had autonomic disorders, 140 (8.9%) had other symptoms such as decreased smell and taste, and 48 (3.3%) had no symptoms after infection. Conclusions The vaccination rate of young and middle-aged people in Lanzhou city of Gansu Province is high. Since the new policy, the infection rate of the novel coronavirus among young and middle-aged people is high, the number of antigen tests is more than nucleic acid tests, most of the infected patients are slight, with fewer critical patients, and the hospitalization rate is low. The peak of infection occurred in early December 2022, and the infection rate was basically zero by February 2023. The main symptoms of COVID-19 infection are mainly respiratory tract, followed by digestive tract and autonomic nervous system disorders, and few patients are completely asymptomatic.
ObjectiveTo analyze the burden of digestive diseases attributed to smoking in China from 1990 to 2019 and forecast its change in the next 10 years. MethodsThe Global Burden of Disease database 2019 was used to analyze the burden of digestive diseases attributed to smoking in China from 1990 to 2019. Joinpoint regression model was used to analyze the time variation trend. A time series model was used to predict the burden of digestive diseases attributable to smoking over the next 10 years. ResultsIn 2019, there were 12 900 deaths from digestive diseases attributed to smoking in China, with a DALY of 398 600 years, a crude death rate of 0.91/100 000 and a crude DALY rate of 28.02/100 000. The attributed standardized mortality rate was 0.69 per 100 000, and the standardized DALY rate was 19.79 per 100 000, which was higher than the global level. In 2019, the standardized mortality rate and DALY rate of males were higher than those of females (1.48/ 100 000 vs. 0.11/ 100 000, 38.42/ 100 000 vs. 293/100 000), and the standardized rates of males and females showed a downward trend over time. In 2019, both mortality and DALY rates from digestive diseases attributed to smoking increased with age. ARIMA predicts that over the next 10 years, the burden of disease in the digestive system caused by smoking will decrease significantly. ConclusionFrom 1990 to 2019, the burden of digestive diseases attributed to smoking showed a decreasing trend in China, and the problem of disease burden is more serious in men and the elderly population. A series of effective measures should be taken to reduce the smoking rate in key groups. The burden of digestive diseases caused by smoking will be significantly reduced in the next 10 years.
ObjectiveTo investigate the inhibitory effect of lentivirus-mediated polypyrimidine bundle binding protein-associated splicing factor (PSF) on retinal neovascularization (RNV) in mice model of oxygen-induced retinopathy (OIR).MethodsOne hundred and twelve 5-day-old C57BL/6J mice were randomly divided into normal control group, simple OIR model group, OIR model + lentivirus empty vector treatment group (Vec group) and OIR model + PSF lentivirus treatment group (PSF group), with 16, 32, 32 and 32 mice, respectively. When the mice were 7 days old, the mice in the normal control group were fed in a routine environment, and the mice in the OIR model group, Vec group and PSF group were established OIR model. The mice in the Vec group and PSF group were given an intravitreal injection of 1 μl of lentiviral vector and PSF lentivirus (titer 1×1011 TU/ml) at the age of 12 days. No injection was performed in the normal control group and simple OIR group. RNV was evaluated by counting the number of pre-retinal neovascular cells and analysis of non-perfusion area by immunofluorescent staining of the mouse retina. Real-time quantitative PCR was applied to detect the mRNA expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and hemeoxygenase-1 (HO-1). Western blot analysis was applied to detect the protein expression of Nrf2, HO-1 and PSF. Results Of the normal control group, simple OIR model group, Vec group and PSF group, the number of pre-retinal neovascular cell nuclei were 0.00, 14.36±5.50, 15.67±4.96, 8.13±2.09, the non-perfusion area were 0.00%, (35.71±2.81)%, (36.57±4.53)%, (15.33±4.75)%, respectively. The differences of the number of pre-retinal neovascular cell nuclei and non-perfusion area among 4 groups were significant (F=24.87, 165.70; P＜0.05). Compared with the normal control group, there were more pre-retinal neovascular cell nucleis and larger non-perfusion area in the simple OIR model group and Vec group (P＜0.05). Compared with the simple OIR model group and Vec group, there were lower pre-retinal neovascular cell nucleis and smaller non-perfusion area in the PSF group (P＜0.05). Real-time quantitative PCR and Western blot showed that the mRNA expression of Nrf2, HO-1 (F=53.66, 83.54) and protein expression of Nrf2, HO-1 and PSF (F=58.38, 52.69, 24.79) among 4 groups were significant (P＜0.05). The mRNA expression of Nrf2, HO-1 and protein expression of Nrf2, HO-1 and PSF in the simple OIR model group and Vec group decreased significantly than those in the normal control group (P＜0.05). The mRNA expression of Nrf2, HO-1 and protein expression of Nrf2, HO-1 and PSF in the PSF group were increased significantly than those in the simple OIR model group and Vec group (P＜0.05). model group and Vec group (P＜0.05).ConclusionIntravitreal injection of lentivirus-mediated PSF inhibits RNV in mice model of OIR possibly through up-regulating the expression of Nrf2 and HO-1.
