Abstract: Behavioral and PET/fMRI-data are presented to delineate the functional networks subserving alertness, sustained attention, and vigilance as different aspects of attention intensity. The data suggest that a mostly right-hemisphere frontal, parietal, thalamic, and brainstem network plays an important role in the regulation of attention intensity, irrespective of stimulus modality. Under conditions of phasic alertness there is less right frontal activation reflecting a diminished need for top-down regulation with phasic extrinsic stimulation. Furthermore, a high overlap between the functional networks for alerting and spatial orienting of attention is demonstrated. These findings support the hypothesis of a co-activation of the posterior attention system involved in spatial orienting by the anterior alerting network. Possible implications of these findings for the therapy of neglect are proposed.

The Difference

ABSTRACTBackground: Hypertension is one of the most common diseases, because this disease is suffered byboth men and women, as well as adults and young people. Treatment of hypertension does not onlyrely on medications from the doctor or regulate diet alone, but it is also important to make our bodyalways relaxed. Laughter can help to control blood pressure by reducing endocrine stress andcreating a relaxed condition to deal with relaxation.Objective: The general objective of the study was to determine the effect of laughter therapy ondecreasing elderly blood pressure in UPT Panti Wredha Budhi Dharma Yogyakarta.Methods: The design used in this study is a pre-experimental design study with one group pre-posttestresearch design where there is no control group (comparison). The population in this study wereelderly aged over> 60 years at 55 UPT Panti Wredha Budhi Dharma Yogyakarta. The method oftaking in this study uses total sampling. The sample in this study were 55 elderly. Data analysis wasused to determine the difference in blood pressure before and after laughing therapy with a ratio datascale that was using Pairs T-TestResult: There is an effect of laughing therapy on blood pressure in the elderly at UPT Panti WredhaBudhi Dharma Yogyakarta marked with a significant value of 0.000 (P <0.05)

Salah satu stressor utama yang terjadi pada anak saat hospitalisasi adalah nyeri yang juga dapat menimbulkan trauma. Tindakan pemasangan Intravena Fluid Drip (IVFD) yang dilakukan pada anak yang dihospitalisasi dapat menimbulkan nyeri akibat cedera jaringan tubuh (kulit). Teknik distraksi audio merupakan tindakan yang dirasa tepat untuk mengurangi nyeri yang ditimbulkan. Tujuan penelitian untuk mengetahui pengaruh teknik distraksi audio terhadap penurunan skala nyeri pemasangan IVFD pada anak prasekolah.Desain penelitian ini adalah pre experimental designwithstatic group comparison dengan menggunakan analisa data uji t tidak berpasangan. Sampel pada penelitian ini berjumlah 32 orang anak prasekolah yang dilakukan pemasangan IVFD dengan metode non probability sampling dengan teknik purposive sampling. Pengukuran skala nyeri menggunakan observasi Face, Leg, Activity, Cry, and Consolability Scale (FLACC Scale).Hasil penelitian didapatkan perbedaan nilai rata-rata skala nyeri antara kelompok intervensi dan kelompok kontrol dengan p value = 0,001 (p < α 0,05). Hasil penelitian ini menunjukkan bahwa terdapat pengaruh teknik distraksi audio terhadap penurunan skala nyeri saat pemasangan IVFD pada anak prasekolah di RSUD Dr. H. Ibnu Sutowo Baturaja. Perawat sebaiknya menerapkan pemberian teknik distraksi audio dalam standar operasional prosedur pemasangan IVFD sebagai salah satu terapi nonfarmakologi pada anak prasekolah yang akan dilakukan pemasangan IVFD.
