PERBANDINGAN METODE ORTODROMIK DAN ANTIDROMIK PEMERIKSAAN KECEPATAN HANTAR SARAF SENSORIS NERVUS MEDIANUS DAN NERVUS ULNARIS PADA PASIEN NEUROPATI

Salah satu penyebab neuropati tersering pada ekstremitas atas adalah penekanan pada nervus medianus dan nervus ulnaris. Pemeriksaan kecepatan hantar saraf (KHS) sensoris sering dipraktikkan untuk mengidentifikasi ada atau tidaknya jejas/kelainan pada saraf yang diduga mengalami neuropati. Metode pemeriksaan KHS sensoris yang sering dipakai adalah ortodromik dan antidromik. Tujuan penelitian ini addalah untuk membandingkan pemeriksaan KHS sensorik ortodromik dengan antidromik yang menggunakan rangsang sinyal dengan arah yang berbeda. Penelitian cross sectional di RSUP dr. Mohammad Hoesin Palembang periode 15 Juli-15 September 2019 pada 64 subjek yang dicurigai menderita neuropati nervus medianus dan ulnaris yang memenuhi kriteria inklusi dan eksklusi, masing-masing dilakukan pemeriksaan KHS sensorik metode ortodromik dan antidromik, kemudian dibandingkan hasil elektroneuromiogramnya. Analisis data menggunakan uji hipotesis komparatif kappa. Hasil analisa statistik menunjukkan keeratan kesesuaian yang “kuat” dan bermakna dengan nilai k = 0,61-0,80 p  <0,05 antara kedua metode ortodromik dan antidromik pada nervus medianus, sementara pada nervus ulnaris keeratan kesesuaian bervariasi, yakni pada durasi KHS dengan keeratan “sedang” k = 0,601 p <0,05, dan pada latensi serta amplitude KHS dengan keeratan “cukup” nilai k = 0,21-0,40 p <0,05. Kesimpulan penelitian ini adalah metode pengukuran KHS sensorik memiliki keeratan kesesuaian yang secara keseluruhan cukup baik sehingga kedua metode dapat digunakan dan mampu memberikan interpretasi kelainan yang serupa dalam pemeriksaan neuropat

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

The surgical safety checklist and patient outcomes after surgery: a prospective observational cohort study, systematic review and meta-analysis

© 2017 British Journal of Anaesthesia Background: The surgical safety checklist is widely used to improve the quality of perioperative care. However, clinicians continue to debate the clinical effectiveness of this tool. Methods: Prospective analysis of data from the International Surgical Outcomes Study (ISOS), an international observational study of elective in-patient surgery, accompanied by a systematic review and meta-analysis of published literature. The exposure was surgical safety checklist use. The primary outcome was in-hospital mortality and the secondary outcome was postoperative complications. In the ISOS cohort, a multivariable multi-level generalized linear model was used to test associations. To further contextualise these findings, we included the results from the ISOS cohort in a meta-analysis. Results are reported as odds ratios (OR) with 95% confidence intervals. Results: We included 44 814 patients from 497 hospitals in 27 countries in the ISOS analysis. There were 40 245 (89.8%) patients exposed to the checklist, whilst 7508 (16.8%) sustained ≥1 postoperative complications and 207 (0.5%) died before hospital discharge. Checklist exposure was associated with reduced mortality [odds ratio (OR) 0.49 (0.32–0.77); P\u3c0.01], but no difference in complication rates [OR 1.02 (0.88–1.19); P=0.75]. In a systematic review, we screened 3732 records and identified 11 eligible studies of 453 292 patients including the ISOS cohort. Checklist exposure was associated with both reduced postoperative mortality [OR 0.75 (0.62–0.92); P\u3c0.01; I2=87%] and reduced complication rates [OR 0.73 (0.61–0.88); P\u3c0.01; I2=89%). Conclusions: Patients exposed to a surgical safety checklist experience better postoperative outcomes, but this could simply reflect wider quality of care in hospitals where checklist use is routine
