Abstract Background Antibiotic-associated diarrhea (AAD) is a common problem among elderly inpatients because many elderly patients are admitted for pneumonia or other conditions that necessitate antibiotic treatment. In the super aging population, more patients are suffering from pneumonia than before, but the incidence or risk factors for AAD among many elderly patients have not been well scrutinized. Methods We conducted a retrospective cohort study of elderly patients diagnosed with pneumonia from April 2014 to March 2019 who were admitted to the Department of General Medicine of a Tertiary Care Hospital in Japan. Patients (≥ 65 years of age) who were diagnosed with bacterial pneumonia or aspiration pneumonia and treated with antibiotics were included. We defined AAD by diarrhea with more than three loose or watery stools per day and included patients who had these symptoms for either one day or two or more consecutive days. We also assessed the length of hospital stay and in-hospital mortality. The potential risk factors for AAD included age, sex, body weight, body mass index, smoking, alcohol, activities of daily living (ADL), comorbidities, vital signs, laboratories, the severity of pneumonia, antibiotic and other medication use. Results There were 1,067 patients, the mean age was 83 years, and men accounted for 59 %. β-Lactamase inhibitors were frequently prescribed antibiotics in 703 patients (66 %), and proton pump inhibitors (PPIs) were also commonly administered (48 %). AAD developed in 322 patients (30 %). The multivariate logistic regression model showed that β-lactamase inhibitors (OR 1.43, 95 % CI 1.05–1.95) and PPIs (OR 1.37, 95 % CI 1.03–1.83) were associated with AAD as well as age (OR 1.03 per year, 95 % CI 1.01–1.05). Conclusions AAD was common among elderly inpatients with pneumonia, and β-lactamase inhibitors and PPIs were associated with AAD. Strict use of such medication should be considered to decrease the risk of AAD.

Abstract Background Clostridium difficile infection (CDI) is a relevant healthcare burden worldwide and one of the leading causes for nosocomial diarrhea. Besides mild courses, the development of a severe infection can occur and has a relevant impact on healthcare costs and patient outcome.Methods We conducted a retrospective cohort study over a 4 year-long period to analyze the incidence of CDI and the contributing risk factors for a severe course at a tertiary care clinic. Independent risk factors were determined by a multivariable logistic regression analysis.Results A total of 761 CDI cases were identified in the study period, thereof 612 (80.4%) cases were nosocomially acquired. The mean incidence for a CDI was 0.42 cases per 1000 patient-days. A severe CDI occurred in 131 cases (17.2%). Independent risk factors for a severe course were pulmonary disease, a Charlson comorbidity index >3, and a preceding antibiotic therapy within three months with glycopeptides (vancomycin/teicoplanin) and/or aminoglycosides.Conclusions This study highlights the relevant burden of CDI in hospitals. Moreover, it underscores that specific knowledge of risk factors contributing to severe CDI is crucial to optimize treatment, infection prevention measures and to guide clinical monitoring and therapy strategy.

Abstract Background: Refractoriness to platelet transfusion is an understudied phenomenon in critically ill patients. Our objective was to evaluate the prevalence, risk factors and clinical outcomes of platelet refractoriness among patients in a tertiary-care intensive care unit (ICU).Methods: A retrospective cohort study included all patients (age >14 years) who were admitted to a tertiary-care medical-surgical ICU between 2011 and 2016 and received ≥2 platelet transfusions during their ICU stay. We calculated platelet increment (PI) and corrected count increment (CCI). Results: A total of 267 patients were enrolled in the study, collectively receiving 1357 transfusions with a median of 3 (interquartile range: 2-6) transfusions per patient. The median pretransfusion platelet count was 31.0 x109/L (interquartile range: 16.0, 50.0) with a median PI of 6 x109/L (interquartile range: -5, 24). The prevalence of platelet transfusion refractoriness was 54.8% based on PI and 57.0% based on CCI. The two methods had excellent concordance in diagnosing refractoriness (kappa coefficient: 0.939). Refractoriness was more common in patients admitted by Hepatology, Liver Transplant, and Hematology services (69.7%, 69.2%, and 55.6%, respectively). On multivariable logistic regression, younger age was the only significant predictor of refractoriness (odds ratio per year increment: 0.975, 95% CI: 0.951-0.999). Finally, refractoriness was associated with increased length of stay in the ICU (p=0.02), but not with mortality.Conclusions: We demonstrated excellent concordance between PI and CCI for the diagnosis of platelet transfusion refractoriness. Platelet transfusion refractoriness was highly (>50%) prevalent in critically ill patients. However, it was not associated with increased mortality.

Background. Refractoriness to platelet transfusion is an understudied phenomenon in critically ill patients. Our objective was to evaluate the prevalence, risk factors, and clinical outcomes of platelet refractoriness among patients in a tertiary-care intensive care unit (ICU). Methods. A retrospective cohort study included all patients (age >14 years) who were admitted to a tertiary-care medical-surgical ICU between 2011 and 2016 and received ≥2 platelet transfusions during their ICU stay. We calculated platelet increment (PI) and corrected count increment (CCI). Results. A total of 267 patients were enrolled in the study, collectively receiving 1357 transfusions with a median of 4.0 (interquartile range: 2.0, 6.0) transfusions per patient. The median pretransfusion platelet count was 31000.0 × 106/L (interquartile range: 16000.0, 50000.0). The median PI was 6000 × 106/L. The prevalence of platelet transfusion refractoriness was 54.8% based on PI < 10000 × 106/L and 57.0% based on CCI <5000. Patients admitted under hepatology/liver transplant had the highest rates of platelet refractoriness (69.6%), while those under general surgery had the lowest rate (43.2%). Younger age, nontrauma admission, and larger spleen size were associated with platelet refractoriness. Finally, refractoriness was associated with increased length of stay in the ICU ( p  = 0.02), but not with mortality. Conclusions. Platelet transfusion refractoriness was highly (>50%) prevalent in ICU patients. However, it was not associated with increased mortality.

Study Design: A retrospective cohort study. Objective: The world was unprecedentedly struck by the new coronavirus in December 2019. Consequently, lockdown measures were imposed by many governments. Health-care services were reserved for emergencies and malignancies. Nevertheless, many patients who urgently needed these services did not present. This study estimates the impact of COVID-19 and lockdown measures on the patients’ flow in the outpatient clinic (OPC) and the operations for laryngeal and/or oropharyngeal neoplasms. Methods: This study is a retrospective cohort study performed in otolaryngology department of a tertiary care hospital which is a major referral center. All patients who attended the OPC and all operations performed for laryngeal and/or oropharyngeal neoplasms were counted from February 1, 2020 to May 31, 2020 and compared with the previous year as a reference. Results: In 2020, the number of patients attending the otolaryngology OPC and the laryngeal and/or oropharyngeal surgeries showed a major drop, especially after imposing the lockdown measures. The total number of these operations in April and May 2019 dropped by 79% for the same period in 2020. Conclusion: An estimate of 79% of patients, who had been presenting for laryngeal and/or oropharyngeal neoplasms, did not show up due to indirect COVID-19 effect.
