Background: The prevalence of multidrug-resistant organisms (MDRO) is gradually increasing in the global scope, causing serious burden to patients and society, which is an important public health problem.
Objective: To analyze the distribution and trend of MDROs and provide a reference for hospital infection control.
Methods: Collected data on MDROs infections among inpatients in a Grade III Level A hospital in Suzhou from 2015 to 2021, including drug-resistant bacteria strains and specimen sources, etc. Mantel-Haenszel test was used to evaluate the trend of infection rates over the years and SPSS version 26.0 was used for statistics analysis.
Results: The hospital infection rate showed an overall downward trend across the seven-year period, ranging from 1.53% to 2.10%. According to the analysis of change of drug-resistant bacteria strains, the highest infection rate was (63.74%), followed by (46.37%), (24.87%), (13.14%) and (0.42%). The results of Mantel-Haenszel test showed that there was a linear relationship between the detection rate of and and the time (<0.001), but the correlation was not strong (R = 0.136; R = 0.139). The overall detection rate of the five pathogens also increased (<0.001). The majority of the specimens, mainly from sputum, airway secretions, and midstream urine, had a detection rate of over 70%.
Conclusion: Our data showed that the detection rate of MDROs generally increased from 2015 to 2021, although the hospital infection rate displayed a declining trend. Among the detection rate MDROs, the highest was , and the lowest was . It is necessary to enhance the prevention, control, and management of MDROs infections in the clinical practice.

Inpatient Hospitalizations for COVID-19 Among Patients With Prader-Willi Syndrome: A National Inpatient Sample Analysis.

Prader-Willi syndrome (PWS) is a genetic disorder associated with baseline respiratory impairment caused by multiple contributing etiologies. While this may be expected to increase the risk of severe COVID-19 infections in PWS patients, survey studies have suggested paradoxically low disease severity. To better characterize the course of COVID-19 infection in patients with PWS, this study analyses the outcomes of hospitalizations for COVID-19 among patients with and without PWS.

Background: Infections caused by extended-spectrum β-lactamase-producing Enterobacterales (ESBL-E) are increasing in the United States. Although many risk factor scoring tools exist, many are specific to bloodstream isolates and may not represent all patient populations. The purpose of this study was to create and validate an institution-specific scoring tool for select ESBL-E of non-urinary origin based on previously identified risk factors.

Background: The increasing prevalence of type 2 diabetes mellitus (T2DM) in lower and middle - income countries call for preventive public health interventions. Studies from Africa including those from Ghana, consistently reveal high T2DM-related mortality rates. While previous research in the Ho municipality has primarily examined risk factors, comorbidity, and quality of life of T2DM patients, this study specifically investigated mortality predictors among these patients.
