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.

Ventral Incisional Hernia

Background: Ventral incisional hernia (VIH) is one of the most common post-operative complications following abdominal surgery. The objective of this study was to evaluate the rate and risk factors associated with development of a ventral incisional hernia (VIH).Methods: Patients who underwent major abdominal surgery between 2010 and 2012 at a single institution were included in this retrospective cohort study. Data were collected from medical records. The primary outcome was clinical or radiological evidence of incisional hernia; explanatory variables were patient demographics and potential clinico-pathological risk factors for hernia development.Results: A total of 295 patients who underwent laparotomy were analysed. 45 (15.25%) patients were found to have a ventral incisional hernia on follow-up. The median time to development of hernia was 351 days. There were equal numbers of elective (N=22) and emergency (N=23) operations that developed an incisional hernia. Of the explanatory variables considered diabetes, hypertension (HTN) and body mass index (BMI) had persistent significant positive associations with the development of an incisional hernia. On univariable analysis diabetes (HR = 2.73, p-value = 0.004) and hypertension (HR =2.17, p-value = 0.016) were identified as independent risk factors for hernia development. BMI was also significantly associated with development of an incisional hernia on univariate analysis, but due to missing data this did not reach statistical significance on multivariable analysis.Conclusions: Although there are several risk factors to development of VIH, diabetes and HTN were associated with development of incisional hernia in our study. BMI also appears to be an important determinant of development of VIH. Further research in this area is likely to identify an at-risk subset of patients, who may benefit from weight loss prior to surgery or prophylactic mesh post-laparotomy.

Osseointegration of a dental implant may encounter a variety of problems caused by various factors, as prior health-related problems, patients� habits and the technique of the implant inserting. Retrospective cohort study of 70 patients who received implants between January 2011- April 2016 in one dental unit, with Kaplan-Meier method to calculate the probability of implants�s survival at 60 months. The analysis included demographic data, age, gender, medical history, behavior risk factors, type and location of the implant. For this cohort the implants�survival for the first 6 months was 92.86% compared to the number of patients and 97.56% compared to the number of total implants performed, with a cumulative failure rate of 2.43% after 60 months. Failures were focused exclusively on posterior mandible implants, on the percentage of 6.17%, odds ratio (OR) for these failures being 16.76 (P = 0.05) compared with other localisations of implants, exclusively in men with median age of 42 years.
