Reactions of pulmonary emphysema patients before and after VRS - Forcusing on the rehabilitation, activity, surgery -

今まで内科的治療が主体であった肺気腫に対して,近年外科的治療(Volume Reduction Surgery 以後VRSと略す)が行われるようになった｡VRSを受ける患者の看護では,手術前後において, リハビリテーション(以後リハビリと略す)や機能回復に向けてのケアが必要不可欠とされる。そこで,本研究は肺気腫患者の適切な看護援助を検討するために,手術前後に示す肺気腫患者のリハビリや活動に対する反応を明らかにすることを目的とした｡対象者は当病棟に入院している肺気腫患者8名(VRS手術前8名,手術後はそのうちの6名である)で, リハビリ, 日常生活活動,呼吸,手術などについて,面接ならびに観察による調査を行った｡分析の結果,手術前においてリハビリでは≪義務感≫,頑張って行えば呼吸が楽になるという≪期待感≫,≪サポート≫,≪不安≫が,活動では≪活動の制限≫,手術では呼吸が楽になるのではという≪期待感≫,≪おまかせ≫,≪いちかばちかの賭け≫,≪不安≫,≪回復に向けての欲求の高まり≫が明らかになった｡手術後においてリハビリでは≪呼吸が楽になるための手段≫が, 日常生活活動では≪今の状態よりは良くなると いう期待感≫が,手術では≪達成感≫ と≪身体的苦痛≫が,将来については≪ささやかな欲求≫が明らかになった｡Pulmonary emphysema has been mainly treated with medicine, but recently VRS(volume reduction surgery) has been receiving much attention. In nursing care for VRS patients, it is important to help the patient improve his/her daily activities and recover physical function smoothly after surgery. The purpose of this study is to clarify the reactions of pulmonary emphysema patients before and after VRS for appropriate nursing. The subjects were eight pulmonary emphysema patients at a ward in Okayama University Hospital, but six of them completed both before and after VRS data collection. The data were collected by interview and observation, and from medical and nursing records. Contents of the interview included rehabilitation, daily activities, respiratory symptoms, operative stress, and so on. The results were as follows : , , , and on rehabilitation, on activity, , , , , and on surgery were extracted as pre-operative patients's reactions. on rehabilitation, on activity, and on surgery, on future were extracted as post-operative patients's reactions

Predictors for orthopaedic surgery in patients with rheumatoid arthritis: results from a retrospective cohort study of 1010 patients diagnosed from 1972 to 2009 and followed up until 2015

<p><b>Objectives</b>: To investigate how patient characteristics, time of diagnosis, and treatment affect the need for orthopaedic surgery in patients with rheumatoid arthritis (RA).</p> <p><b>Method</b>: We reviewed the medical history of 1544 patients diagnosed with RA at Haukeland University Hospital in Bergen, Norway, from 1972 to 2009, of whom 1010 (mean age 57 years, 69% women) were included in the present study. Relevant orthopaedic procedures were obtained from the Norwegian Arthoplasty Register and the hospital’s administrative patient records. In total, 693 procedures (joint synovectomies 22%, arthrodeses 21%, prostheses 41%, and forefoot procedures 12%) were performed in 315 patients. Survival analyses were completed to evaluate the impact of different factors such as age, gender, radiographic changes, and year of diagnosis, on the risk of undergoing surgery.</p> <p><b>Results</b>: Patients diagnosed in 1972–1985 and 1986–1998 had a relative risk of undergoing surgery of 2.4 and 2.2 (p < 0.001), respectively, compared to patients diagnosed in 1999–2009. Radiographic changes at diagnosis and female gender were also significant risk factors. Anti-rheumatic medication was significantly different in the three time periods.</p> <p><b>Conclusion</b>: Patients with a diagnosis in the early years had a greatly increased risk of having orthopaedic surgery performed. This is probably due to the year of diagnosis being a proxy for the type and intensity of medical treatment.</p

Persistence of EBV Antigen-Specific CD8 T Cell Clonotypes during Homeostatic Immune Reconstitution in Cancer Patients.

Persistent viruses are kept in check by specific lymphocytes. The clonal T cell receptor (TCR) repertoire against Epstein-Barr virus (EBV), once established following primary infection, exhibits a robust stability over time. However, the determinants contributing to this long-term persistence are still poorly characterized. Taking advantage of an in vivo clinical setting where lymphocyte homeostasis was transiently perturbed, we studied EBV antigen-specific CD8 T cells before and after non-myeloablative lympho-depleting chemotherapy of melanoma patients. Despite more advanced T cell differentiation, patients T cells showed clonal composition comparable to healthy individuals, sharing a preference for TRBV20 and TRBV29 gene segment usage and several co-dominant public TCR clonotypes. Moreover, our data revealed the presence of relatively few dominant EBV antigen-specific T cell clonotypes, which mostly persisted following transient lympho-depletion (TLD) and lymphocyte recovery, likely related to absence of EBV reactivation and de novo T cell priming in these patients. Interestingly, persisting clonotypes frequently co-expressed memory/homing-associated genes (CD27, IL7R, EOMES, CD62L/SELL and CCR5) supporting the notion that they are particularly important for long-lasting CD8 T cell responses. Nevertheless, the clonal composition of EBV-specific CD8 T cells was preserved over time with the presence of the same dominant clonotypes after non-myeloablative chemotherapy. The observed clonotype persistence demonstrates high robustness of CD8 T cell homeostasis and reconstitution
