Vaccination efficacy in patients with chronic lymphocytic leukemia
Leuk Lymphoma. 2022 Oct 21:1-15. doi: 10.1080/10428194.2022.2133538. Online ahead of print.ABSTRACTChronic lymphocytic leukemia (CLL) is a disorder of mature malignant B cells with multiple elements of immune dysfunction. Infections are common in CLL patients due to complex immunodeficiency. Vaccines are used as preventative measures for common diseases including influenza, pneumococcus, tetanus/diphtheria and shingles in the general population. Vaccines are utilized to mitigate this risk, although there have been some concerns regarding the efficacy of vaccines in the CLL population due to the inherent complex immune dysf...

Fight Aging! Newsletter, September 19th 2022
Conclusion Use of the Khavinson peptides and melatonin in combination in this way, at this dose, negatively impacts the thymus, producing a reduction in active tissue and increase in atrophy to fatty tissue. The degree to which this atrophy occurred is greater than one would expect to take place over nine months of aging at this stage of life. Why did this outcome occur, given the animal studies showing thymic regrowth, and the studies showing reduced later life mortality following use of thymogen? We can only speculate. Firstly, the dose makes the poison, and the dosing here may have been too high, too frequ...

Variability in non-core vaccination rates of dogs and cats in veterinary clinics across the United States
Vaccine. 2022 Jan 13:S0264-410X(22)00006-8. doi: 10.1016/j.vaccine.2022.01.003. Online ahead of print.ABSTRACTVaccination guidelines for dogs and cats indicate that core vaccines (for dogs, rabies, distemper, adenovirus, parvovirus; for cats, feline parvovirus, herpes virus-1, calicivirus) are essential to maintain health, and that non-core vaccines be administered according to a clinician's assessment of a pet's risk of exposure and susceptibility to infection. A reliance on individual risk assessment introduces the potential for between-practice inconsistencies in non-core vaccine recommendations. A study was initiated t...

Vaccination coverage in hematological patients undergoing chemotherapy: Should we move towards personalized vaccination?
CONCLUSION: Despite vaccination opportunities, the complexity of these specific recommendations and the lack of communication between the health actors could explain the suboptimal vaccination coverage in this high-risk population. A proactive attitude of all actors in the city and hospital, including better patient information and a personalized and evolving vaccination schedule to help GPs to coordinate vaccination would allow to improve vaccine coverage.PMID:34740475 | DOI:10.1016/j.vaccine.2021.10.040

The objective of this study is to quantify the overall and cancer type-specific risks of subsequent primary cancers (SPCs) among adult-onset cancer survivors by first primary cancer (FPC) types and sex. Among 1,537,101 survivors (mean age, 60.4 years; 48.8% women), 156,442 SPC cases and 88,818 SPC deaths occurred during 11,197,890 person-years of follow-up (mean, 7.3 years). Among men, the overall risk of developing any SPCs was statistically significantly higher for 18 of the 30 FPC types, and risk of dying from any SPCs was statistically significantly higher for 27 of 30 FPC types as compared with risks in the general po...

The management of hematologic malignancies during the COVID-19 pandemic.
Authors: Hus I, Salomon-Perzyński A, Tomasiewicz K, Robak T Abstract Introduction: Patients with hematological malignancies have experienced a more severe clinical course of COVID-19 and higher mortality than those with solid tumors and those without cancer. The ongoing pandemic poses many challenges in assuring the correct and timely diagnosis of hemato-oncology patients as well as the optimal treatment. Areas covered: The present paper reviews current data on the incidence and clinical course of COVID-19 in patients with hematological malignancies. A literature review of the MEDLINE database for articles was con...

From “Serum Sickness” to “Xenosialitis”: Past, Present, and Future Significance of the Non-human Sialic Acid Neu5Gc
Conclusions and Perspectives In this review, we have discussed important milestones from the early description of “Serum-sickness” as being due to antibodies directed against Neu5Gc epitopes all the way to the present-day therapeutic implications of these antibodies in cancer therapy. Some of these milestones have been represented in a concise timeline (Figure 6). While the “Xenosialitis” hypothesis is well-supported in the human-like mouse models, it has yet to be conclusively proven in humans. It remains to be seen if “Xenosialitis” plays a role in other uniquely-human dis...

B Cell Reconstitution and Influencing Factors After Hematopoietic Stem Cell Transplantation in Children
Nicolaas G. van der Maas, Dagmar Berghuis, Mirjam van der Burg and Arjan C. Lankester* Willem-Alexander Children's Hospital, Department of Pediatrics and Laboratory for Pediatric Immunology, Leiden University Medical Center, Leiden, Netherlands B cell reconstitution after hematopoietic stem cell transplantation (HSCT) is variable and influenced by different patient, donor, and treatment related factors. In this review we describe B cell reconstitution after pediatric allogeneic HST, including the kinetics of reconstitution of the different B cell subsets and the development of the B cell repertoire, and d...

How Scientists Are Treating Breast Cancer Using the Immune System
As a pharmacist, Kathy James considers herself well educated about the importance of getting regular cancer screenings. Even though the 55-year-old had no history of cancer in her family, she never skipped her regular mammograms, and she gave herself regular breast exams. So she was dumbfounded when, during one of those self-exams in May 2017, she felt a marble-size lump in her left breast. A visit to the doctor confirmed it. “The radiologist came in with his hands in his pockets and looked down and said, ‘It doesn’t look good,'” James says. After a biopsy, James and her husband learned she had meta...
