Objective To compare quality of life for HIV infected people or AIDS patients and their family members of noninfected people in two counties (Zizhong and Zhaojue) with high AIDS morbidity and high HIV infective rates. Methods The quality of life for HIV infected people or AIDS patients and 162 of their family members and 97 people noninfected HIV/AIDS was measured by a questionnaire containing the generic quality of life inventory 74 (GQOLI-74) and the social support scale (SSS). Data were analyzed with SPSS. Results Total GQOLI-74 scores and each of the four dimensionality scores were significantly lower for HIV/AIDS people and their family members compared with noninfected people (total score for HIV/AIDS people 52.20 [9.41]; family members 60.46 [11.92]; noninfected people 66.36 [8.90] (Plt;0.01)). Scores for each of the disease status (physical function, psychological function, social function and material status) were all lower compared with noninfected people (all comparisons Plt;0.01). GQOLI-74 scores of HIV/AIDS people were significantly correlated with disease status and social support, but age, education level and substance abuse did not show significantly correlation. Conclusions The quality of life for HIV infected people or AIDS patients and their families is significantly lower than the general population, and this is particularly related to the severity of their disease and lack of social support.
Objective To assess the value of procalcitonin ( PCT) in serum and percentage of infected cells ( PIC) in bronchoalveolar lavage fluid ( BALF) for the diagnosis of early ventilator-associatedpneumonia ( VAP) .Methods A prospective observational study was conducted in a teaching hospital. The patients consecutively admitted to the intensive care unit from January 2011 to June 2012, who received mechanical ventilation for more than 48h and clinically suspected for VAP, were recruited in the study.Patients with infection outside the lungs and previous diagnosed infection were excluded. PCT was detected and bronchoalveolar lavage was performed in the day when VAP was diagnosed. BALF cells were stained by May-Grunwald Giemsa ( MGG) for counting 100 phagocytic cells and calculating infected cells ( ICs )percentage.Results 76 of all 421 patients were enrolled in this study, 64 of which were diagnosed, 12 were under-diagnosed. The PCT [ ( 3. 48 ±1. 46) ng/mL vs. ( 1. 53 ±0. 60) ng/mL] and PIC [ ( 3. 11 ±1. 47) % vs. ( 1. 08 ±0. 29) % ] were significant higher in the patients with VAP. The threshold of 2 ng/mL of PCT and 2% of PIC corresponded to sensitivity of 78. 12% and 78. 12% , and specificity of 75. 00% and 91. 67% , respectively. The area under the receiver operating characteristic ( ROC) curve was 0. 87 ( 95% CI 78. 9%-95. 9% ) and 0. 874 ( 95% CI 79. 2% -94. 9% ) , respectively. The area under ROC curve was 0. 979, and the sensitivity was 97. 36% , specificity was 97. 36% when the two cutoff values were both achieved. Conclusion PCT and PIC are useful markers to diagnose early VAP quickly and conveniently and allow early antibiotic treatment of patients with suspected VAP.
ObjectiveTo summarize the effectiveness of bone transport with unilateral external fixator combined with locked plate internal fixation in treatment of infected tibial nonunion.MethodsBetween January 2010 and December 2014, 23 patients with infected tibial nonunion were treated with bone transport with unilateral external fixator combined with locked plate internal fixation. There were 19 males and 4 females with an average age of 37.8 years (range, 19-54 years). The mean length of the bone defect was 6.5 cm (range, 5.2-8.1 cm). The number of previous operations ranged from 2 to 4 times, with an average of 2.5 times. The time from injury to this treatment was 7-23 months, with an average of 11.8 months. The time of bone transport, time of the external fixation, fracture healing time, external fixation index, healing index, and complication were recorded; and the Association for the Study and Application of the Methods of Ilizarov (ASAMI) bone healing and function scores were used to evaluate the effectiveness.ResultsAll patients were followed up 3-6 years with an average of 4.8 years. Wounds and bone defects healed in all patients. No complication such as infection recurrence, nonunion, re-fracture, malunion, iatrogenic nerve paralysis, or stiffness of knee and ankle joints occurred. Five patients had needle infections which were treated by local care and no deep infection occurred. The time of bone transport was 65-120 days (mean, 75.6 days); the time of the external fixation was 75-145 days (mean, 97.8 days); the fracture healing time was 4-17 months (mean, 8.7 months); the external fixation index was 18-28 days/cm (mean, 22.4 days/cm); and the healing index was 31-52 days/cm (mean, 40.2 days/cm). At last follow-up, according to ASAMI criteria, the result of bone healing was excellent in 15 cases and good in 8 cases, and the result of function was excellent in 18 cases and good in 5 cases, all with the excellent and good rate of 100%.ConclusionFor infected tibial nonunion, bone transport with unilateral external fixator combined with locked plate internal fixation can reduce the time of external fixation and related complications, with a satisfactory effectiveness.
Objective To review the research progress of new antibacterial hydrogels in the treatment of infected wounds in the field of biomedicine, in order to provide new methods and ideas for clinical treatment of infected wounds. Methods The research literature on antibacterial hydrogels at home and abroad was extensively reviewed in recent years, and the antibacterial hydrogels for the treatment of infected wounds were classified and summarized. Results Antibacterial hydrogels can be divided into three categories: inherent antibacterial hydrogels, antibacterial agent release hydrogels, and environmental response antibacterial hydrogels. The advantages and disadvantages of antibacterial materials, antibacterial mechanism, antibacterial ability, and biocompatibility were discussed respectively. Inherent antibacterial hydrogels have the characteristics of wide source, low cost, and simple preparation, but their antibacterial ability is relatively weak. New antimicrobial substances are added to antibacterial agent release hydrogels, such as antimicrobial peptides, metal ions, graphene materials, etc., providing a new therapeutic strategy for alternative antibiotic therapy. On the basis of the antibacterial material, environmental promoting factors such as photothermal effect, pH value, and magnetic force are added to the environmental response antibacterial hydrogels, which synergically enhances the antibacterial ability of the hydrogel, improves the precise regulation function and bionic effect of the hydrogel. ConclusionThe selection of a variety of materials, the addition of a variety of antibacterial agents, and the effect of various promoting factors make composite hydrogels show multiple characteristics. The development of antibacterial hydrogels that can effectively address practical clinical applications remains a significant challenge. In the future, expanding the application range of antibacterial hydrogels, constructing drug-loaded hydrogels, and developing intelligent hydrogels are still new areas that need to be explored and studied.
ObjectiveTo evaluate the clinical efficacy of surgical intervention combined with endoscopic ultrasound-guided transluminal drainage in the treatment of infected pancreatic necrosis (IPN). MethodsA retrospective, historical control study was conducted. A total of 98 patients with acute pancreatitis (AP) complicated with IPN who met the inclusion and exclusion criteria and were admitted to the Third People’s Hospital of Chengdu from June 2016 to January 2023 were selected as the research objects. The endoscopic ultrasound-guided transluminal drainage was carried out in our hospital in June 2020. In this study, patients treated before May 2020 were divided into the non-EUS group (52 cases), and patients treated after June 2020 were divided into the EUS group (46 cases). The baseline data, surgical intervention, length of hospital stay, length of intensive care unit (ICU) stay, infection time, incidence of multiple organ dysfunction syndrome (MODS), survival situation, short-term and long-term complications, and other indicators were compared between the two groups. ResultsThe number of percutaneous catheter drainage (PCD, 1.0 vs. 1.0), the number of PCD drainage tube (1.0 vs. 2.0), the number of retroperitoneal debridement drainage (1.0 vs. 2.0), the total length of hospital stay (42.0 d vs. 45.5 d), the length of ICU stay (11.0 d vs. 14.0 d), the length of infection time (10.5 d vs. 18.5 d), the incidences of MODS [43.5% (20/46) vs. 67.3% (35/52)] and residual infection [28.3% (13/46) vs.48.1% (25/52)] in the EUS group were shorter (or lower) than those in the non-EUS group (P<0.05); but there were no significant differences in the number of endoscopic pancreatic stent implantation, the number of laparotomy, the number of laparoscopic surgery, and the incidences of abdominal bleeding, gastrointestinal fistula, gastrointestinal obstruction, chronic pancreatic fistula, chronic pancreatitis and incisional hernia between the two groups (P>0.05). ConclusionFor patients with AP complicated with IPN, surgical intervention combined with endoscopic ultrasound-guided transluminal drainage can reduce the number of PCD and drainage tube, shorten the total length of hospital stay, the length of ICU stay and infection, as well as reduce the incidences of MODS and residual infection.
