Controlled non-randomised before-after study evaluating the impact of a focused recommendation card on vaccination rates of oncological patients-The Easy Vaccination in Oncology (EVO) strategy.

OBJECTIVE: By implementing a focused must-have vaccination strategy (Easy Vaccination in Oncology [EVO]), we aimed to increase rates for high-impact vaccinations (Streptococcus pneumoniae, influenza, herpes zoster and hepatitis B) in the at-risk population of oncological patients. METHODS: In this German multicentre interventional non-randomised controlled two-arm open trial with repeated cross-sectional data collection, we evaluated the EVO strategy as an easy to implement approach. Vaccination rates were assessed in the outpatient setting and re-assessed after 3 months. A generalised linear mixed model (GLMM) was used to assess the primary endpoint (Streptococcus pneumoniae vaccination rates according to recommendations), taking clustering within clinics into account. RESULTS: Vaccination rates substantially increased in the intervention group; Streptococcus pneumoniae +21.5% (+16.7% according to recommendations), influenza +12.2%, herpes zoster +13.3% (+13.6% age group 50+), and hepatitis B +11%. Vaccination rates in the control group tended to decrease or increase only moderately (-5.8% [-3.8%], +7.4%, +2.1% [1.4%], and -1.7%, respectively). GLMM showed significant effect of the intervention (OR 7.50, 95% CI 2.18-25.80, p = 0.001). CONCLUSION: This easy-to-implement and resource-saving approach has the potential to increase vaccination rates in oncological patients and to have a considerable impact protecting oncological patients from preventable infectious diseases. CLINICAL TRIAL REGISTRATION: The study was registered at the German Resister for Clinical Studies (DRKS) under DRKS00020118.

Immunochemotherapy - A Missed Opportunity for Metastasized Malignant Melanoma? Reporting a Therapeutic Success with Checkpoint Inhibitor Rechallenge after Cytotoxic Immuno-Priming in a Heavily Pretreated Patient.

Treatment of metastasized malignant melanoma still has very limited therapeutic options. After exhaustion of immuno-checkpoint inhibition (ICI) and potentially targeted therapy, no promising alternatives are currently available. We report on an 83-year-old patient suffering from disseminated metastatic melanoma who showed an almost complete response to ICI following chemotherapy, after repeated failure of different regimens including two nonresponsive regimens of ICI. The presented outcome suggests a cytotoxic immuno-priming, facilitating a response to prior nonresponsive ICI. As this concept has not been established until now for malignant melanoma, in contrast to multiple other cancer entities, our case report corroborates previous evidence and therefore suggests a new treatment option, which should be researched further.

Retrospective comparison of reinfusion procedures and subsequent leukopenia in autologous stem cell transplantation.

Standard operating procedures for autologous stem cell transplantation (SCT) aim to guarantee best possible engraftment. Three procedures are routinely used for transplant infusion: regular bag infusion (Procedure 1), injection via syringe (Procedure 2), and combination of regular bag infusion and syringe (Procedure 3). We conducted a retrospective analysis of all autologous stem cell transplants done in the hematology department of the Vivantes Clinic Neukoelln in Berlin, Germany, between January 1, 2016 and March 4, 2017. Of the total of 69 patients, 17 underwent Procedure 1, 32 Procedure 2, and 20 Procedure 3. Although speed of transplant reinfusion differed significantly between procedure types, these differences had no effect on duration of leukopenia. However, duration of leukopenia did correlate with need for blood transfusion and use of antibiotics. Our findings contradict the general perception that very rapid reinfusion is necessary. Nevertheless, considering the limitations of this study (retrospective, single center, small sample size) and that longer duration of aplasia is associated with greater need for intervention, efficient transplant reinfusion is advisable. More research is needed regarding timeliness and type of procedure used.

HIV-Associated Lung Cancer.

Lung cancer (LC) is one of the most common non-AIDS (acquired immune deficiency syndrome)-defining malignancies. It occurs more frequently in persons living with human immunodeficiency virus (PLWHIV) than in the HIV-negative population. Compared to their HIV-negative counterparts, patients are usually younger and diagnosed at more advanced stages. The pathogenesis of LC in PLWHIV is not fully understood, but immunosuppression in combination with chronic infection and the oncogenic effects of smoking and HIV itself all seem to play a role. Currently, no established preventive screening is available, making smoking cessation the most promising preventive measure. Treatment protocols and standards are the same as for the general population. Notably, immuno-oncology will also become standard of care in a significant subset of HIV-infected patients with LC. As drug interactions and hematological toxicity must be taken into account, a multidisciplinary approach should include a physician experienced in the treatment of HIV. Only limited data is available on novel targeted therapies and checkpoint inhibitors in the setting of HIV.

Cross-sectional study assessing HIV-related knowledge, attitudes and behavior in the Namibian truck transport sector: Readjusting HIV prevention programs in the workplace.

The objectives of this study were to assess the current status of HIV-related knowledge, attitudes, and behavior (KAB) of employees in the private transport sector in Namibia and to compare companies with established HIV workplace program (WPPs) with those that have recently initiated the implementation of such programs. The study was designed as a cross-sectional questionnaire-based survey. Between January and March 2011, the survey was conducted in the Namibian truck transport sector in six companies of different sizes. The participants were selected randomly from the workforce. Data collection was based on a KAB questionnaire. The range of correct answers to the survey concerning the knowledge of HIV transmission was 67-95%. Twenty percent of the employees had never been tested for HIV. Additionally, risky sexual behaviors were quite prevalent and included having multiple concurrent partners and the use of sex for incentives. This study revealed that drivers and laborers were especially at risk for such behaviors. The employees of companies with established WPPs were tested for HIV more often than those of companies with new WPPs; however, aside from this difference, only minor differences were observed between the two groups. The findings of this study highlight the need for on-going HIV information and prevention campaigns that focus on the special needs of mobile and low-income workers. WPPs should be tailored accordingly and shift their focus to more practical approaches, such as voluntary counseling and testing (VCT), to increase their effectiveness.

Cross-sectional study assessing HIV related knowledge, attitudes and behavior in Namibian public sector employees in capital and regional settings.

The study objective was to assess the current status of HIV knowledge, attitudes and behavior (KAB) among employees of Namibian ministries. As most HIV campaigning takes place in the capital of Windhoek, an additional aim was to compare Windhoek to four regions (Hardap, Erongo, Oshana, and Caprivi). Between January and March 2011 a cross-sectional survey was conducted in two Namibian ministries, with participants selected randomly from the workforce. Data collection was based on questionnaires. 832 participants were included in the study (51.6% male). Nearly 90% of participants reported to have been tested for HIV before. Knowledge about HIV transmission ranged from 67% to 95% of correct answers, with few differences between the capital and regions. However, a knowledge gap regarding HIV transmission and prevention was seen. In particular, we found significantly lower knowledge regarding transmission from mother-to-child during pregnancy and higher rate of belief in a supernatural role in HIV transmission. In addition, despite many years of HIV prevention activities, a substantial proportion of employees had well-known HIV risk factors including multiple concurrent partnership rates (21%), intergenerational sex (19%), and lower testing rates for men (82% compared to women with 91%).
