Renal and perinephric abscesses in West China Hospital: 10-year retrospective-descriptive study.

ABSTRACT: AIM:To elucidate the clinical, radiological and laboratory pro?les of renal abscess (RA) and perinephric abscess (PNA), along with related treatment and outcome. METHODS:Ninety-eight patients diagnosed with RA or PNA using the primary discharge diagnoses identified from the International Statistical Classification of Diseases and Related Health Problems Tenth Edition (ICD-10) codes (RA: N15.101, PNA: N15.102) between September 2004 and December 2014 in West China Hospital were selected. Medical records including patients' characteristics, symptoms and signs, high-risk factors, radiological features, causative microorganisms and antibiotic-resistance pro?les, treatment approaches, and clinical outcomes were collected and analyzed. RESULTS:The mean age of the patients was 46.49 years with a male to female ratio of 41:57. Lumbar pain (76.5%) and fever (53.1%) were the most common symptoms. Other symptoms and signs included chills (28.6%), anorexia and vomiting (25.5%), lethargy (10.2%), abdominal pain (11.2%), flank mass (12.2%), flank fistula (2.0%), gross hematuria (7.1%), frequency (14.3%), dysuria (9.2%), pyuria (5.1%) and weight loss (1.0%). Painful percussion of the costovertebral angle (87.8%) was the most common physical finding. The main predisposing factors were lithiasis (48.0%), diabetes mellitus (33.7%) followed by history of urological surgery (16.3%), urinary tract infections (14.3%), renal function impairment (13.3%), liver cirrhosis (2.0%), neurogenic bladder (1.0%), renal cyst (1.0%), hydronephrosis (1.0%), chronic hepatitis B (1.0%), post-discectomy (1.0%) and post-colectomy (1.0%). Ultrasound (US) and computed tomography were the most valuable diagnostic tools and US was recommended as the initial diagnostic imaging choice. Escherichia coli (51.4%), Staphylococcus aureus (10.0%) and Klebsiella pneumoniae (8.6%) were the main causative microorganisms. Intravenous antibiotic therapy was necessary while intervention including surgical and nonsurgical approaches were reserved for larger abscesses, multiple abscesses, PNAs and non-responders. CONCLUSION:Heightened alertness, prompt diagnosis, and especially proper antibiotics in conjunction with interventional approaches allow a promising clinical outcome of renal and perinephric abscesses.

Project description:To determine the dynamic changes of pathogenic yeast prevalence and antifungal susceptibility patterns in tertiary hospitals in China, we analyzed 527 yeast isolates preserved in the Research Center for Medical Mycology at Peking University, Beijing, China, between Jan 2010 and Dec 2019 and correctly identified 19 yeast species by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and ribosomal DNA sequencing. Antifungal susceptibility testing was performed following a Sensititre YeastOne colorimetric microdilution panel with nine clinically available antifungals. The Clinical and Laboratory Standards Institute (CLSI)-approved standard M27-A3 (S4) and newly revised clinical breakpoints or species-specific and method-specific epidemiological cutoff values were used for the interpretation of susceptibility test data. In this study, although Candida albicans was the predominant single species, non-C. albicans species constituted >50% of isolates in 6 out of 10 years, and more rare species were present in the recent 5 years. The non-C. albicans species identified most frequently were Candida parapsilosis sensu stricto, Candida tropicalis, and Candida glabrata. The prevalence of fluconazole and voriconazole resistance in the C. parapsilosis sensu stricto population was <3%, but C. tropicalis exhibited decreased susceptibility to fluconazole (42, 57.5%) and voriconazole (31, 42.5%), and 22 (30.1%) C. tropicalis isolates exhibited wild-type minimum inhibitory concentrations (MICs) to posaconazole. Furthermore, fluconazole and voriconazole cross-resistance prevalence in C. tropicalis was 19 (26.1%). The overall prevalence of fluconazole resistance in the C. glabrata population was 14 (26.9%), and prevalence of isolates exhibiting voriconazole non-wild-type MICs was 33 (63.5%). High-level echinocandin resistance was mainly observed in C. glabrata, and the prevalence rates of isolate resistance to anidulafungin, micafungin, and caspofungin were 5 (9.6%), 5 (9.6%), and 4 (7.7%), respectively. Moreover, one C. glabrata isolate showed multidrug resistant to azoles, echinocandins, and flucytosine. Overall, the 10-year surveillance study showed the increasing prevalence of non-C. albicans species over time; the emergence of azole resistance in C. tropicalis and multidrug resistance in C. glabrata over the years reinforced the need for epidemiological surveillance and monitoring.

Project description:The use of coronary catheterization and percutaneous coronary intervention (PCI) is increasing in China, but, to date, there are no nationally representative assessments of the quality of care and outcomes in patients undergoing these procedures.To assess the quality of care and outcomes of patients undergoing coronary catheterization and PCI in China.In a clinical observational study (China PEACE [Patient-Centered Evaluative Assessment of Cardiac Events]-Retrospective CathPCI Study), we used a 2-stage, random sampling strategy to create a nationally representative sample of 11 241 patients undergoing coronary catheterization and PCI at 55 urban Chinese hospitals in calendar years 2001, 2006, and 2011. Data analysis was performed from July 11, 2014, to November 20, 2015.Patient characteristics, treatment patterns, quality of care, and outcomes associated with these procedures and changes over time.Of the 11?241 patients included in the study, the samples included, for 2001, 285 women (weighted percentage, 28.6%); for 2006, 826 women (weighted percentage, 32.2%), and for 2011, 2588 women (weighted percentage, 35.7%). Mean (SD) ages were 58 (8), 60 (11), and 61 (11) years, respectively. Between 2001 and 2011, estimated national rates of hospitalizations for coronary catheterization increased from 26?570 to 452 784 and for PCI, from 9678 to 208 954 (17-fold and 21-fold), respectively. More than half of stable patients undergoing coronary catheterization had nonobstructive coronary artery disease; this amount did not change significantly over time (2001: 60.3% [95% CI, 56.1%-64.5%]; 2011: 57.5% [95% CI, 55.8%-59.3%], P?=?.05 for trend). The proportion of PCI procedures performed via radial approach increased from 3.5% (95% CI, 1.7%-5.3%) in 2001 to 79.0% (95% CI, 77.7%-80.3%) in 2011 (P?<?.?001 for trend). The use of drug-eluting stents (DESs) increased from 18.0% (95% CI, 14.2%-21.7%) in 2001 to 97.3% (95% CI, 96.9%-97.7%) in 2011 (P?<?.001 for trend) largely owing to increased use of domestic DESs. The median length of stay decreased from 14 days (interquartile range [IQR], 9-20) in 2001 to 10 days (IQR, 7-14) in 2011 (P?<?.001 for trend). In-hospital mortality did not change significantly, but both adjusted risk of any bleeding (odds ratio [OR], 0.53 [95% CI, 0.36-0.79], P?<?.001 for trend) and access bleeding (OR, 0.23 [95% CI, 0.12-0.43], P?<?.001) were decreased between 2001 and 2011. The medical records lacked documentation needed to calculate commonly used process metrics including door to balloon times for primary PCI and the prescription of evidence-based medications at discharge.Although the use of catheterization and PCI in China has increased dramatically, we identified critical quality and documentation gaps that represent opportunities to improve care. Our findings can serve as a foundation to guide future quality improvement initiatives in China.

Project description:Introduction: Toxoplasmosis is a parasitic zoonosis and an important cause of abortions, mental retardation, encephalitis, blindness, and death worldwide. Few studies have quantified toxoplasmosis mortality and associated medical conditions in Sub-Saharan Africa. This retrospective hospital-based study aimed to determine the mortality patterns of toxoplasmosis and its comorbidities among in-patients in Tanzania. Methods: Data on causes of death were collected using customized paper-based collection tools. Sources of data included death registers, inpatient registers, and International Classification of Diseases report forms. All death events from January 2006 to December 2015 were collected. Data used in this study is a subset of deaths where the underlying cause of death was toxoplasmosis. Data was analyzed by STATA programme version 13. Results: Thirty-seven public hospitals were involved in the study. A total of 188 deaths due to toxoplasmosis were reported during the 10-years period. Toxoplasmosis deaths accounted for 0.08% (188/247,976) of the total deaths recorded. The age-standardized mortality rate per 100,000 population increased from 0.11 in 2006 to 0.79 in 2015. Most deaths due to toxoplasmosis affected the adult age category. Of the 188 deaths, males accounted for 51.1% while females for 48.9% of the deaths. Dar es Salaam, Mbeya, Pwani, Tanga, and Mwanza contributed to over half (59.05%) of all deaths due to Toxoplasmosis. Of the total deaths due to toxoplasmosis, 70.7% were associated with other medical conditions; which included HIV/AIDS (52.6%), HIV/AIDS+Cryptococcal meningitis (18.8%) and HIV+Pneumocystis pneumonia (6.8%). Conclusion: The age-standardized mortality rate due to toxoplasmosis has been increasing substantially between 2006 and 2015. Most deaths due to toxoplasmosis affected the adult age category and were highly associated with HIV/AIDS. Appropriate interventions are needed to alleviate the burden of toxoplasmosis in Tanzania.

Project description:BACKGROUND:Urgent-start peritoneal dialysis (PD) can help patients with end-stage renal diseases (ESRD) that are referred late to dialysis. However, catheter patency and related complications of urgent-start PD have not been thoroughly clarified. We investigated the clinical outcomes of urgent-start PD in a Chinese cohort. METHODS:We enrolled ESRD patients who received urgent-start PD (starting PD within 14?days after catheter insertion) in our center from January 1, 2006 to December 31, 2014, and followed them up for 10?years. The primary outcome was catheter failure. Secondary outcomes included short-term and long-term complications related to urgent-start PD. RESULTS:Totally 2059 patients (58.9% male, mean age 47.6?±?15.9?years) were enrolled. Few perioperative complications were observed, including significant hemorrhage (n?=?3, 0.1%) and bowel perforation (n?=?0). Early peritonitis occurred in 24 (1.2%) patients (0.28 episodes per patient-year). Within the first month after catheter insertion, functional catheter malfunction occurred in 85 (4.1%) patients, and abdominal wall complications (including hernia, hydrothorax, hydrocele, and leakage) in 36 (1.7%) patients. During a median 36.5 (17.7-61.4) months of follow-up, 75 (3.6%) patients experienced catheter failure, and 291 (14.1%) had death-censoring technique failure. At the end of 1-month, 1 -year, 3-year, and 5-year, catheter patency rate was 97.6, 96.4, 96.2, 96.2%; and technique survival rate was 99.5, 97.0, 90.3, 82.7%, respectively. After adjusting for confounders, every 5-year increase in age was associated with 19% decrease of risk for catheter failure (hazard ratio [HR]: 0.81, 95% confidence interval [CI]: 0.73-0.89). Male sex (HR: 1.43, 95% CI: 1.00-2.04), diabetic nephropathy (HR: 1.56, 95% CI: 1.08-2.25) and low hemoglobin levels (HR: 0.89, 95% CI: 0.81-0.98) were independent risk factors for abdominal wall complications. CONCLUSIONS:Urgent-start PD is a safe and efficacious option for unplanned ESRD patients. A well-trained PD team, a standardized catheter insertion procedure by experienced nephrologists, and a carefully designed initial PD prescription as well as comprehensive follow-up care, might be essential for the successful urgent-start PD program.
