Abstract Background The aim of this study is to identify risk factors associated with the development of severe bacterial infection (SBI) in patient with multiple myeloma (MM) during treatment with bortezomib-containing regimens. Methods A total of 98 patients with MM who were treated with bortezomib-based treatment between 2006 and 2012 were analyzed. Fifty three patients received bortezomib-dexamethasone, 25 patients received bortezomib-melphalan-prednisolone, 15 patients received bortezomib-doxorubicin-dexamethasone and 5 patients received other regimens. They received a total of 427 courses of treatment. The SBI was defined as at least grade 3 neutropenic/non-neutropenic infection by NCI Common Terminology Criteria for Adverse Events version 4.0. Using the logistic regression method, we analyzed risk factors for the development of SBI during each course of treatment. Results Median age of the patients was 62 years and 40.6% (30/98) of patients treated with bortezomib-containing regimens as first-line therapy. The SBI was developed in 57% (56/98) of patients and 19% (81/427) of bortezomib courses. Among 81 episodes of SBI, 42 (53%) episodes were clinically documented infection, 30 (37%) were microbiologically documented infections, and 9 (11%) were fever of unknown origin. The most common type of infection was pneumonia (60%). Poor performance status (ECOG ≥2) (Hazard Ratio [HR] 5.365, 95% Confidence Interval [CI] 2.004-14.364, P =.001) was the only risk factor for the development of SBI in 98 patients. When we analyzed the risk factors for the development of SBI which occurred during each treatment course, poor performance status (ECOG ≥2) (P <.001), early course of treatment (≤2 courses) (P <.001) and pretreatment lymphopenia (absolute lymphocyte count <1.0 x 109/L) (P = .043) were associated with increased risk for developing SBI in each course. These 3 risk factors remained independently significant in multivariate analysis: poor performance status (ECOG ≥2) (HR 3.920, 95% CI 2.305-6.666, P <.001), early course of treatment (≤2 courses) (HR 2.782, 95% CI 1.633-4.740, P <.001) and pretreatment lymphopenia (HR 1.728, 95% CI 1.016-2.937, P = .043). The probability of developing SBI in each treatment course was 5.1% in courses with no risk factor, 14.9% in 1 risk factor, 23.9% in 2 risk factors and 59.5% in 3 risk factors (P <.001, Figure 1). After treatment with bortezomib-containing regimens, patients who experienced SBI showed a significantly shorter overall survival than patients who didn't experienced SBI (median 6.1 month vs. 30.1 months, P = .004) although progression free survival was not different (median 18.1 months vs. 21.9 months, P = .418). The multivariate cox analysis demonstrated that the development of SBI was associated with inferior overall survival (HR 2.440, 95% CI 1.305-4.561, P = .005) as well as male sex (HR 2.323, 95% CI 1.236-4.367, P = .009). Conclusions In conclusion, we identified that poor performance status, early courses of treatment, and lymphopenia at the beginning of each treatment course were the risk factors for the development of SBI in patients with MM during treatment with bortezomib-containing regimens. Close monitoring for the development of SBI and appropriate treatment should be considered in the patients with risk factors. Disclosures: No relevant conflicts of interest to declare.

Introduction Maternal and newborn infections are important causes of mortality but morbidity data from low- and middle-income countries is limited. We used telephone surveillance to estimate infection incidence and risk factors in women and newborns following hospital childbirth in Dar es Salaam. Methods We recruited postnatal women from two tertiary hospitals and conducted telephone interviews 7 and 28 days after delivery. Maternal infection (endometritis, caesarean or perineal wound, or urinary tract infection) and newborn infection (umbilical cord or possible severe bacterial infection) were identified using hospital case-notes at the time of birth and self-reported symptoms. Adjusted Cox regression models were used to assess the association between potential risk-factors and infection. Results We recruited 879 women and interviewed 791 (90%). From day 0–7, 6.7% (49/791) women and 6.2% (51/762) newborns developed infection. Using full follow-up data, the infection rate was higher in women with caesarean childbirth versus women with a vaginal delivery (aHR 1.93, 95%CI 1.11–3.36). Only 24% of women received pre-operative antibiotic prophylaxis before caesarean section. Infection was higher in newborns resuscitated at birth versus newborns who were not resuscitated (aHR 4.45, 95%CI 2.10–9.44). At interview, 66% (37/56) of women and 88% (72/82) of newborns with possible infection had sought health-facility care. Conclusions Telephone surveillance identified a substantial risk of postnatal infection, including cases likely to have been missed by hospital-based data-collection alone. Risk of maternal endometritis and newborn possible severe bacterial infection were consistent with other studies. Caesarean section was the most important risk-factor for maternal infection. Improved implementation of pre-operative antibiotic prophylaxis is urgently required to mitigate this risk.

Common Causes

Dental pulp necrosis is referred to the situation in which the teeth biologically die due to bacterial infection or without bacterial infection. Dental pulp necrosis can be due to a chronic progression of pulpitis, in which the tissue of soft pulp in the tooth dies due to several causes such as trauma or severe bacterial infection. Untreated cavities, multiple invasive treatments for the tooth, and pathological ischemia for dental pulp are among the most common causes for the necrosis process. Usually, the first symptom of dental pulp necrosis is the irritant pain in the tooth only or the surrounding area because of the inflammation. The grade of pain ranges from mild, moderate, to severe pain according to the size of the damage, followed by swelling and discomfort in chewing due to the pressure on the nerve root at the base of the tooth. We aim to review the different etiologies, risk factors, correlations, and clinical outcomes associated with pulp necrosis. To our knowledge, this article is going to be the first comprehensive review of dental pulp necrosis.

Abstract Background China had entered post-elimination era for malaria, however, the imported cases are continuously are a public health concern as the increasing number of cases. In this study we studied the potential predictive factors for prolonged hospital stay for imported malaria patients. Material and Methods We retrospectively collected patients of imported malaria cases data from 2017–2020 in our hospital. we analyzed the data from clinical, epidemiological, geographical, and seasonal points of view, and used cox proportional hazard model to find the predictive factors for prolonged hospital stay. Results We found most of imported cases were from Democratic Republic of the Congo(23%, 34/150) and most cases 74%(26/34) were infected by P. falciparum. Through Edwards Test, no significant seasonality of imported cases were found(χ2 = 2.51 p-value = 0.28). We found bacterial infection(HR = 0.58, p-value = 0.01) and thrombocytopenia(HR = 0.66, p-value = 0.02) were protective factors for discharge, that were, the risk factors for prolonged hospital stay. Conclusions The imported cases are the major risk of malaria in post-elimination era of China. The bacterial infection and thrombocytopenia were the risk factors for prolonged hospital stay.
