The role of optimism in manifesting recovery outcomes after coronary artery bypass graft surgery: A systematic review

Abstract

Objective

Coronary artery bypass graft (CABG) is a major surgery conducted in coronary heart disease management. Postoperative recovery is a crucial process for patients undergoing CABG. This systematic review evaluates current evidence regarding the association between trait optimism and recovery outcomes in patients following coronary artery bypass graft surgery.

Methods

This review followed the Preferred Reporting Items of Systematic Review and Meta-Analysis (PRISMA) 2020 Guideline. The inclusion criteria focused on observational study that examined study participants aged ≥18 years old undergoing elective CABG and measurement of trait optimism with validated methods (i.e. LOT, LOT-R) and at least one recovery outcome. Studies in non-English languages and duplicates were excluded. A systematic literature search was carried out on PubMed, Scopus, and Web of Science electronic databases. Search results were screened based on the eligibility criteria. The Newcastle-Ottawa Scale was used to assess the quality of each included study.

Results

The search yielded a total of 1853 articles, in which 7 articles fulfilled the eligibility criteria and were subsequently included in the analysis. Measurement of trait optimism was conducted on 1276 patients who underwent a non-emergency/elective CABG. Optimism was significantly associated with several categories of recovery, including reduced rehospitalization rate, complications, pain, and physical symptoms along with improved quality of life, rate of return to normal life, and psychological status.

Conclusion

Our review showed that trait optimism was associated with recovery outcomes following CABG surgery. However, the heterogeneity of recovery outcomes may hamper the clinical benefit of trait optimism in CABG. (PROSPERO CRD42022301882).

Catatan Belajar Paru: Bronkiektasis

Bronkiektasis Pendahuluan Bronkiektasis adalah suatu kondisi yang ditandai secara patologis oleh peradangan saluran napas dan dilatasi bronkus permanen , serta secara klinis oleh batuk, produksi dahak, dan eksaserbasi dengan infeksi saluran pernapasan berulang. Definisi Bronkiektasis adalah kelainan morfologis yang terdiri dari pelebaran bronkus yang abnormal dan permanen akibat rusaknya komponen elastik dan muskular dinding bronkus. Epidemiologi 1. P revalensi bronkiektasis non-cystic fibrosis diperkirakan sebesar 52 kasus per 100.000, dengan jumlah total kasus diperkirakan lebih dari 110.000 di Amerika Serikat.  2. Studi yang lebih baru menunjukkan prevalensi yang lebih tinggi yaitu 139 kasus per 100.000 orang.  3. Prevalensi bronkiektasis meningkat seiring bertambahnya usia dan tampaknya lebih umum pada wanita (1,3 hingga 1,6 kali lebih tinggi) dan orang Asia (2,5 hingga 3,9 kali lebih tinggi dibandingkan dengan orang Kaukasia dan Afrika Amerika).  Etiologi Bronkiektas...

Overfill vs Underfill Hypothesis in Edema

The overfill and underfill theories describe two different mechanisms that explain the development of edema, particularly in conditions like nephrotic syndrome and cirrhosis. Overfill Theory The overfill theory suggests that edema results from primary renal sodium retention. Key points include: 1. Primary Renal Sodium Retention: The kidneys retain sodium and water independently of the systemic circulation. 2. Increased Blood Volume: The retained sodium and water increase the blood volume, raising the hydrostatic pressure in the capillaries. 3. Fluid Leakage: The elevated hydrostatic pressure causes fluid to leak from the capillaries into the interstitial spaces, leading to edema. This mechanism is often associated with conditions where the kidneys are directly affected, such as certain types of nephrotic syndrome (cause retention of salt and water), acute/chronic kidney disease (reduced GFR, salt&water retention) Underfill Theory The underfill theory posits that edema is due to dec...

Ketoasidosis Diabetikum: Gula, Keton, dan Asam Bertemu di Darah--Kisah yang Ternyata Tak Seindah Itu

Kukira kita asam dan garam Dan kita bertemu di belanga Kisah yang ternyata tak seindah itu (Hati-hati di jalan; Tulus, 2022) Definisi Trias KAD: ketonemia, hiperglikemia, asidosis metabolik Etiologi Penyakit atau Infeksi: Infeksi adalah pemicu umum DKA karena meningkatkan kebutuhan insulin. Contoh infeksi meliputi pneumonia, infeksi saluran kemih, dan sepsis. Kondisi akut lainnya seperti stroke, infark miokard, dan pankreatitis juga dapat memicu DKA. Pengobatan yang Tidak Adekuat atau Terputus: Ketidakpatuhan terhadap regimen pengobatan insulin dapat menyebabkan DKA. Pengurangan dosis insulin yang tidak tepat atau penghentian pengobatan secara tiba-tiba. Stres Fisik atau Emosional: Kondisi stres berat baik fisik maupun emosional dapat meningkatkan hormon kontra-regulator seperti kortisol dan adrenalin, yang memperburuk hiperglikemia dan ketogenesis. Penggunaan Obat Tertentu: Penggunaan obat kortikosteroid dapat meningkatkan risiko DKA. Obat-obatan seperti tiazid, beta-blocker, dan sim...
