"Sindrom koroner akut (SKA) merupakan salah satu kegawatan kardiovaskular diInstalasi Gawat Darurat (IGD). Tatalaksana SKA yang ada saat ini membutuhkan waktuminimal 3 jam untuk menentukan apakah pasien dirawat atau dipulangkan, hal ini akanberdampak pada kepadatan IGD dan pemborosan biaya perawatan. European Society ofCardiology merekomendasikan algoritma 0/1 jam pada pasien dengan gambaran EKGnon elevasi segmen ST (NEST) dengan menggunakan high sensitive troponin T (hscTnT)dalam menegakkan atau penapisan infark miokard akut non elevasi segmen ST(IMA-NEST). Penelitian ini bertujuan untuk membandingkan nilai diagnostik hs-cTnTjam ke-1 dan jam ke-3 pada terduga SKA non elevasi segmen ST dengan awitan nyeridada kurang dari 6 jam. Desain penelitian potong lintang. Sebanyak 100 subjekpenelitian yang diambil secara konsekutif sampling. Sensitivitas, spesifisitas, nilaiprediksi positif, dan nilai prediksi negatif kadar hs-cTnT 0/1 jam secara berurutanadalah 93,75%, 98,81%, 93,75%, 98,81%, sementara sensitivitas, spesifisitas, nilaiprediksi positif, dan nilai prediksi negatif kadar hs-cTnT 0/3 jam secara berurutanadalah 87,50%, 96,81%, 93,33% 97,65%. Pemeriksaan hs-cTnT 0/1 jam dapatdipergunakan dalam rule in dan rule out terduga IMA-NEST dengan awitan nyeri dadakurang dari 6 jam.

Acute coronary syndrome (ACS) is one of the cardiovascular events in an EmergencyInstallation (ED). The patients management of ACS required at least 3 hours todetermined whether the patient hospitalized or outpatient, these would increased EDscrowded and high cost treatment. The European Society of Cardiology recommended a0/1 hour algorithm in patients with ECG showed non ST segment elevationusing highsensitive troponin T (hs-cTnT) parameter to rule in or rule out non ST segmentelevation myocard infarct (NSTEMI).We aimed to compare diagnostic values of hscTnTat the 1st and 3rd hour in NSTEMI with chest pain onset less than 6 hours. Studydesign was cross sectional. A total of 100 subjects enrolled by consecutive samplingmethod. Sensitivity, specificity, positive predictive value, and negative predictive valueof hs-cTnT 0/1 hours were 93.75%, 98.81%, 93.75%, 98.81%, while sensitivity,specificity, positive predictive value, and the negative predictive value of hs-cTnT 0/3hours were 87.50%, 96.81%, 93.33%, 97.65%. Hs-cTnT 0/1 hour test can be used inrule in and rule out suspect NSTEMI with the chest pain onset less than 6 hours."

"Latar Belakang. Masalah kesehatan yang kerap muncul pada olahraga berlari banyak disebabkan oleh dehidrasi. Penelitian ini bertujuan untuk mengetahui laju keringat pelari rekreasional terlatih agar masalah kesehatatan terkait dehidrasi dapat dicegah. Metode. Penelitian eksperimental ini melibatkan 23 pelari rekreasional terlatih yang diminta untuk berlari selama satu jam pada pagi hari di ruang terbuka kota Jakarta. Berat badan subjek ditimbang sebelum dan setelah berlari. Selisih berat badan kemudian dikalkulasikan dengan volume asupan cairan selama latihan untuk memperoleh laju keringat. Hasil. Berdasarkan persentase kehilangan berat badan, 18 dari 23 subjek mengalami dehidrasi setelah berlari selama satu jam, dengan rata-rata mencapai 1.4 (1.4 ± 0,4) %. Selama latihan, rata-rata subjek minum sebanyak 311 mL. Rata-rata laju keringat yang dikeluarkan subjek mencapai 1.2 (1.2 ± 0,3) L/jam. Laju keringat memiliki korelasi positif dengan luas permukaan tubuh (r = 0,71, p < 0,01) dan juga indeks massa tubuh (r= 0,77, p < 0,01) subjek. Tidak ditemukan adanya korelasi signifikan antara laju keringat dengan intensitas dan riwayat latihan subjek. (p > 0,05) Kesimpulan. Tingginya laju keringat subjek masih belum diimbangi oleh asupan minum subjek, sehingga menyebabkan terjadinya dehidrasi. Untuk itu diperlukan edukasi mengenai strategi rehidrasi yang sesuai dengan kebutuhan individual untuk mencegah terjadinya masalah kesehatan akibat dehidrasi

Background. Health problems that often appear in running are mostly caused by dehydration. This research aims to know the sweat rate of trained recreational runners so that health problems related to dehydration can be prevented. Method. This experimental study involved 23 trained recreational runners who were asked to run for one hour on the morning day in the open space of the city of Jakarta. Subject was weighed (with precision up to 0,1 kg) before and after running. Body weight that were loss during running is then calculated with the volume of fluid intake to get the sweat rate. Results. Based on the percentage of body weight loss, 18 out of 23 subjects were dehydrated after running for one hour, with the average reaches 1.4 (1.4 ± 0,4)%. During practice, the average subject drinks as much as 311 mL. The average sweat rate of the subject was 1.2 (1.2 ± 0,3) L / hour. Sweat rate has a positive correlation with body surface area (r = 0,71, p <0,01) and also body mass index (r = 0,77, p <0,01). There was no significant correlation found between the sweat rate and the exercise intensity nor training history of the subject. (p> 0,05) Conclusion. The high sweat rate of the subject was still not matched by their fluid intake, causing dehydration. Therefore education is needed regarding the rehydration strategy that suits the individual needs to prevent health problems related to dehydration."
