Extended-spectrum β-lactamases-producing Escherichia coli , Klebsiella pneumoniae , and Proteus mirabilis (ESBL-producing-EKP) are an increasingly common cause of childhood urinary tract infection (UTI) worldwide. Recognizing the risk factors and antimicrobial resistance patterns may guide new management in this population. This is a retrospective cohort study of over 5 years in Taiwan (2017–2021). Inclusion criteria are hospitalized pediatric patients with the discharge diagnosis of UTI caused by E. coli , Klebsiella pneumoniae , or Proteus mirabilis. ESBL-producing-EKP and non-ESBL-producing-EKP UTI cases were reviewed for characteristics , urinary isolate antibiotics resistance, and clinical outcomes. The incidence rate of ESBL-producing-EKP UTI increased over the study period (Overall incidence rate: 14.1 %, 46/327 patients). Recent antibiotic therapy in ≤6 months (X2 = 11.83, p < 0.01) and a preterm gestational history (X2 = 8.11, p < 0.05) were associated with an increased risk. The proportion of patients with these two risk factors for ESBL acquisition were 37.5 % (X2 = 9.08, p < 0.05). The co-resistance rate of ESBL-producing-EKP to other antimicrobial agents was 63.0 % for gentamicin, 56.5 % for trimethoprim-sulfamethoxazole, 52.2 % for ciprofloxacin, 4.3 % for amikacin, and 2.2 % for imipenem. The generalized linear model analysis identified a significantly longer length of stay (β: 2.85; 95 % confidence interval [CI]: 1.14–4.56; p < 0.01) and intensive care unit duration (β: 5.86; 95 % CI: 1.59–10.12; p < 0.01) among patients with ESBL-producing-EKP UTI. Amikacin should be considered as an alternative antimicrobial choice beyond carbapenems for ESBL-producing-EKP UTI, especially in the context of carbapenem-resistant E. coli/Klebsiella pneumoniae (CRE/CRKP) emergence.

Introduction: Fluoroquinolone exposure is reportedly associated with a higher risk of tendon disorders, tendonitis, or tendon rupture. However, studies in East Asian populations have not confirmed these risks in patients with comorbidities or concomitant medication use. This cohort study was designed to investigate the associations among fluoroquinolone exposure, comorbidities, medication use, and tendon disorders in Taiwan. Materials and Methods: This population-based, nationwide, observational, cohort study used data from the National Health Insurance Research database in Taiwan, a nationwide claims database that covers more than 99% of the Taiwanese population. The study period was from January 2000 to December 2015, and the median follow-up time was 11.05 ± 10.91 years. Patients who were exposed to fluoroquinolones for more than three consecutive days were enrolled, and patients without fluoroquinolone exposure who were matched by age, sex, and index year were enrolled as controls. The associations of comorbidities and concomitant medication use with tendon disorder occurrence were analyzed using Cox regression models. Results: The incidence of tendon disorders were 6.61 and 3.34 per 105 person-years in patients with and without fluoroquinolone exposure, respectively (adjusted hazard ratio, 1.423; 95% confidence interval [1.02,1.87]; p = 0.021). Sensitivity analyses yielded similar results. Patients under 18 and over 60 years with fluoroquinolone exposure; those with chronic kidney disease, diabetes, rheumatologic disease, cardiac disease, lipid disorder, or obesity; and those who concomitantly used statins, aromatase inhibitors, or glucocorticoids, had a significantly higher risk of tendon disorders. Conclusion: The long-term risk of tendon disorders was higher in patients with fluoroquinolone exposure than in those without fluoroquinolone exposure. Clinicians should assess the benefits and risks of fluoroquinolone use in patients at high risk of tendon disorders who require fluoroquinolone administration. [ABSTRACT FROM AUTHOR]

Purpose: With recent advances in surgical techniques and instruments, orthopedic surgeons are better equipped to treat metastatic bone disease. There has also been considerable progress in the non-surgical treatment of cancers, specifically in improving the survival rate of patients with advanced cancer. However, it remains unclear whether surgical resection of a metastatic bone lesion poses additional risk to the survival of patients with advanced cancer. Patients and Methods: This study utilized data from the National Health Insurance Research Database (NHIRD) in Taiwan between 2000 and 2015. Patients aged ≥ 18 years, who had been recently diagnosed with bone metastases (BM), were enrolled and assigned to either the surgery or non-surgery groups. The demographic characteristics were analyzed, and the adjusted hazard ratios (aHR) of mortality were calculated using Cox regression analysis. Results: Of the 4,549,226 individuals in the inpatient database of the NHIRD, 83,536 patients with BM were enrolled in this study. Among them, 8802 underwent surgical resection for skeletal metastatic lesion and 66,098 did not. Altogether, 28,691 patients died, including 2798 (31.8%) in the surgery group and 25,893 (39.2%) in the non-surgery group. The aHR for mortality was 0.7-fold lower in the surgery group (p < 0.001). Conclusion: This study demonstrates that surgical resection of metastatic bone lesions did not pose any additional risk to survival outcomes. Thus, we believe that surgery, if indicated, could have a competitive role in the management of metastatic bone disease. [ABSTRACT FROM AUTHOR]

Methicillin-resistant Staphylococcus aureus (MRSA) is an important human pathogen that causes serious infectious diseases and was endemic in hospitals by the late 1960s. Beginning with its first report in the late 1990s, the rapid emergence of community-associated MRSA (CA-MRSA) worldwide responsible for a wide spectrum of diseases ranging from minor skin infections to fatal necrotizing pneumonia has been found in previously healthy individuals without established risk factors for MRSA acquisition. Recently, various virulence determinants unique to CA-MRSA have been uncovered, which explain how the pathogen spreads easily and causes severe CA-MRSA infections among humans. However, the role of Panton-Valentine leukocidin (PVL) in the pathogenesis of CA-MRSA infection is currently a matter of much debate because of conflicting data from epidemiologic studies of CA-MRSA infections and various murine disease models. Identifying specialized pathogenic traits of CA-MRSA and the concerted regulation of these factors remains a challenge that will foster development of vaccines and therapies designed to control CA-MRSA infections. This review focuses on the current status of molecular epidemiology associated with CA-MRSA in Taiwan and progresses toward understanding the enhanced virulence properties of CA-MRSA, with an emphasis on the role of Panton-Valentine leukocidin.

Abstract: A case of furuncular myiasis was reported for the first time in a 29-year-old young Taiwanese traveler returning from an ecotourism in Peru. Furuncle–like lesions were observed on the top of his head and he complained of crawling sensations within his scalp. The invasive larva of botfly, Dermatobia hominis, was extruded from the furuncular lesion of the patient. Awareness of cutaneous myiasis for clinicians should be considered for a patient who has a furuncular lesion and has recently returned from a botfly–endemic area. [Copyright &y& Elsevier]

• Childhood abuse experiences affect children physiologically and psychologically • psychiatric disorder risk was significantly higher in victims of child abuse • Those caring for abused children should be aware of their risk of psychiatric disorder Child abuse affects children physiologically and psychologically, increasing the risk of future psychiatric disorders. To assess whether child abuse victims have a higher incidence of future psychiatric disorders or substance abuse. The participants consisted of a nationwide, population-based cohort selected in accordance with the Taiwan National Health Insurance Research Database. All children were enrolled between 2000 and 2015. This was a retrospective study with a matched-cohort design. Children who experienced child abuse were identified using International Classification of Disease codes and compared with children who had not experienced child abuse by measuring rates of anxiety disorders, depressive disorders, bipolar disorders, sleep disorders, posttraumatic stress disorder/acute stress disorder, eating disorders, substance-related disorders (alcohol use disorder and illicit drug use disorder), psychotic disorders, and organic mental disorders. The psychiatric disorder risk was significantly higher in victims of child abuse than in controls (adjusted hazard ratio, 2.15; 95 % confidence interval, 1.92–2.40; P < 0.001). The Kaplan-Meier analysis revealed a significantly higher 15-year cumulative incidence of psychiatric disorders among child abuse victims than among controls (394.57 vs. 317.56 events per 100,000 person-years; log-rank test, P < 0.001). In Taiwan, child abuse is associated with increased psychiatric disorder and substance abuse risk. Individuals involved in caring for abused children, including family members, pediatricians, nurses, and social workers, as well as policy makers, should be aware of this risk. Early referral of child abuse victims to pediatric psychiatrists may help detect high-risk cases and facilitate early intervention. [ABSTRACT FROM AUTHOR]
