The term resilience, which has been present in science for almost half a century, stands for the capacity of some system needed to overcome an amount of disturbance from the environment in order to avoid a change to another stable state. In medicine, the concept of resilience means the ability to deal with daily stress and disturbance to our homeostasis with the intention of protecting it from disturbance. With aging, the organism becomes more sensitive to environmental impacts and more susceptible to changes. Mental disturbances and a decline in psychological resilience in older people are potentiated with many social and environmental factors along with a subjective perception of decreasing health. Distinct from findings in younger age groups, mental and physical medical conditions in older people are closely associated with each other, sharing common mechanisms and potentiating each other’s development. Increased inflammation and oxidative stress have been recognized as the main driving mechanisms in the development of aging diseases. This paper aims to reveal, through a translational approach, physiological and molecular mechanisms of emotional distress and low psychological resilience in older individuals as driving mechanisms for the accelerated development of chronic aging diseases, and to systematize the available information sources on strategies for mitigation of low resilience in order to prevent chronic diseases.

We report the unique pathogenesis and presentation of a rapidly progressive B‐cell lymphoma in a 3‐year‐old female cynomolgus monkey on day 50 of a 13‐week toxicity study. Clinical pathology evaluation revealed a marked leukocytosis with bicytopenia. A serum protein electrophoresis was consistent with monoclonal gammopathy. The architecture of the lymph node, spleen, and thymus were variably effaced by neoplastic cells, which also infiltrated other tissues. Immunohistochemistry of the affected tissues confirmed a predominant population of CD20+, CD79a+, CD3‐, CD68‐, and CD34‐neoplastic cells. The full data best support a diagnosis of Stage V lymphoma. Nextgen sequencing and negative prestudy serology results suggested a recent infection by macaque lymphocryptovirus (mLCV) with a unique transcriptional profile comparable with a rarely observed direct LCV infection model. This infection model might be associated with a temporary lack of an LCV antigen‐specific cytotoxic T‐cell adaptive immune response. Consistent with the established mechanisms of LCV‐related lymphoproliferation, MYC and BCL2L11 gene expression were increased and decreased, respectively. While there was no overt immunosuppression, immunophenotyping revealed the index animal had a relatively low NK cell count, which further decreased by >50% on day 24 of the study. In addition to the temporary lack of adaptive immunity, the low NK cell counts were suggestive of an impaired innate immunity to control the virally‐transformed cells and the subsequent unchecked lymphoproliferation. To our knowledge, this is the first report of a Stage V lymphoma with a unique pathogenesis in an otherwise immunocompetent cynomolgus monkey.

SAŽETAK: Šećerna bolest sa svojim komplikacijama uzrokuje 9 % ukupne smrtnosti diljem svijeta. Periferna arterijska bolest, uz kardiovaskularne bolesti, najčešća je komplikacija šećerne bolesti, čija prevalencija raste s dobi i duljinom trajanja dijabetesa. Specifičnost periferne arterijske bolesti u dijabetičara jest difuzno zahvaćanje arterijskog sustava, poglavito potkoljeničnih arterija. Posljedično tomu, dijabetes je i dalje glavni uzrok malih i velikih amputacija ekstremiteta, što, uz smanjenje kvalitete života, znatno utječe i na preživljenje bolesnika. Budući da razvijena aterosklerotska bolest uključuje niz komplikacija iz stručne domene različitih užih specijalnosti, poput dijabetičkog stopala, u dijagnostici i liječenju nužno je organizirati multidisciplinarne timove. U tu svrhu u Općoj bolnici "Dr. Josip Benčević" u Slavonskom Brodu organiziran je multidisciplinarni tim sa svrhom ranog prepoznavanja periferne arterijske bolesti te pravodobnog liječenja. Dosadašnje iskustvo iz svakodnevne kliničke prakse pokazuje da je za pravilno funkcioniranje tima nužno imati precizan dijagnostičko-terapijski algoritam kako bi se izbjegle duge liste čekanja za slikovnu obradu koja uključuje dupleks ultrazvuk i višeslojnu kompjutoriziranu tomografiju. Dijagnostički algoritam temeljio se na vrijednostima gležanjskog indeksa, a njegova vrijednost i klinička slika usmjeruju i određuju stupanj hitnosti i tip slikovne obrade. Integriranjem algoritma u on-line registar baze podataka dobili smo mogućnost lakšeg praćenja stope učestalosti, uspješnosti liječenja i ovisnosti o unesenim varijablama. Nadamo se da će takav način rada rezultirati ranijim otkrivanjem simptomatske bolesti, a time i znatnim smanjenjem amputacija donjih ekstremiteta te naposljetku i smrtnosti. SUMMARY: Diabetes and its complications causes up to 9% of total mortality worldwide. Peripheral arterial disease is, in addition to cardiovascular diseases, the most common complication of diabetes with a prevalence that increases with age and the duration of diabetes. The specificity of peripheral artery disease in diabetics is the diffuse involvement of the arterial system, especially the popliteal arteries. Consequently, diabetes is still the main cause of small and large limb amputations, which, in addition to a reduction in the quality of life, significantly affects the survival of patients. Since the developed of atherosclerotic disease involves a number of complications from the professional domain of various subspecialties, such as diabetic foot, it is necessary to organize multidisciplinary teams for the diagnostic and therapeutic purposes. For this purpose, the General Hospital "Dr. Josip Benčević" in Slavonski Brod organized a multidisciplinary team with the goal of early recognition of peripheral artery disease and application of timely treatment. Experience from everyday clinical practice indicates that proper functioning of the team requires an accurate diagnostic and therapeutic algorithm to avoid long waiting lists for imaging, which includes Co...

Introduction: Rifampicin is currently used to treat various bacterial infections, with the most significant application in the treatment of tuberculosis. Dose-independent side effects of the drug can lead to the development of various coagulation disorders, among which disseminated intravascular coagulation is the most dangerous. The mechanism of coagulopathy itself is multifactorial, but it is thought to be mediated by an immune response (formation of antigen-antibody complexes) and consequent damage to platelets and the vascular endothelium. Patient concerns: A 66-year-old woman, with numerous comorbidities including chronic renal failure, condition after implantation of a permanent pacemaker, and a positive blood culture for Staphylococcus aureus , presented with spontaneous bleeding in the muscle wall, and in the clinical picture of hemorrhagic shock. Diagnosis: Knowing the multifactorial mechanism of rifampicin-induced coagulopathy, possible factors were considered, such as infections, comorbidities, drug use and drug-drug interactions, pathological laboratory parameters, and coagulograms. Clinical presentation of abdominal pain and intra-abdominal mass, with laboratory verification of prolonged activated partial thromboplastin time and computed tomography-proven hematoma suspected of acute bleeding, redirects clinical suspicion of drug-induced coagulopathy. Interventions: By discontinuing rifapicin and administering vitamin K and fresh frozen plasma, normalization of laboratory coagulation parameters was achieved. Bleeding from the muscle wall required correction of acute anemia with red cell concentrates, surgical intervention, and additional antibiotic therapy for secondary infection of the operative wound. Outcomes: At the end of 6 weeks of antibiotic (antistaphylococcal) therapy (due to the basic suspicion of possible infectious endocarditis), the normalization of inflammatory parameters occurred with a sterile control blood culture and a normal coagulogram. Conclusion: Clinicians should be aware of the possible side effects of the administered drugs, especially taking into account the overall clinical picture of a patient, including comorbidities and possible drug interactions.
