Risk Factors Promoting Hypertensive Crises: Evidence From a Longitudinal Study

Background Current knowledge about risk factors promoting hypertensive crisis originates from retrospective data. Therefore, potential risk factors of hypertensive crisis were assessed in a prospective longitudinal study. Methods Eighty-nine patients of the medical outpatient unit at the University Hospital of Bern (Bern, Switzerland) with previously diagnosed hypertension participated in this study. At baseline, 33 potential risk factors were assessed. All patients were followed-up for the outcome of hypertensive crisis. Cox regression models were used to detect relationships between risk factors and hypertensive crisis (defined as acute rise of systolic blood pressure (BP) ≥200mmHg and/or diastolic BP ≥120mmHg). Results The mean duration of follow-up was 1.6 ± 0.3 years (range 1.0-2.4 years). Four patients (4.5%) were lost to follow-up. Thirteen patients (15.3%) experienced hypertensive crisis during follow-up. Several potential risk factors were significantly associated with hypertensive crisis: female sex, higher grades of obesity, the presence of a hypertensive or coronary heart disease, the presence of a somatoform disorder, a higher number of antihypertensive drugs, and nonadherence to medication. As measured by the hazard ratio, nonadherence was the most important factor associated with hypertensive crisis (hazard ratio 5.88, 95% confidence interval 1.59-21.77, P < 0.01). Conclusions This study identified several potential risk factors of hypertensive crisis. Results of this study are consistent with the hypothesis that improvement of medical adherence in antihypertensive therapy would help to prevent hypertensive crises. However, larger studies are needed to assess potential confounding, other risk factors and the possibility of interaction between predictor

LOCAL WISDOM OF BAUMATA SOCIETY IN KUPANG IN CONSIDERING THE NATURE PERSERVATION

A research on local wisdom in the nature preservation of Baumata has been conducted from February to March 2014. It held in the Village of East Baumata, Taebenu Sub district, Kupang regency, East Nusa Tenggara (NTT) in order to know what is the local wisdom owned by Baumata villages in the preservation of nature and environment around them. The method used in this research is descriptive qualitative. The data is taken by interviews and direct observation. Researchers explore the village of East Baumata to observe and conduct the interviews with community consisting of the village, traditional leaders, healers (shaman) and ordinary people. The results obtained from this study is clearly wisdom view of local communities Baumata in the preservation of nature, namely the presence of fine custom ('adat sanctions') related actions that damage the environment. Besides that all the families which surveyed, were seen planting and maintaining plants for food, medicine and ornamental plants in the yard. One other interesting thing is all the families surveyed had livestock in the household and their concepts and apply the principles of the triangle of life "mansian - muit - nasi, na bua" which means humans, livestock, and forests is an integral and mutual dependency

Diversitas dan Distribusi Alga Merah (Rhodophyta) di Perairan Pulau Ternate

Red algae (Rhodophyta) are low-level plants that generally grow attached to certain substrates such as coral, mud, sand, rocks and other massive objects. This type of algae take nutrients from the substrate by diffusion through the walls from its thallus. This alga prefers habitat of clear waters that have substrate base of coral, dead coral, volcanic rocks or massive objects. Red algae can be found in intertidal, subtidal to coastal areas with strong waves and currents as well as in mangrove area. This study aims to determine the diversity and distribution patterns and associations of red algae in seagrass ecosystems and coastal coral reefs of Ternate Island. The method used in this study is a descriptive method with sampling by line-transect quadrat (1x1 meter). The sampling locations were divided into three stations. Data were analyzed descriptively and the number of red algae (Rhodophyta) found at each station was included in a distribution map based on depth and density index. The results showed that the total number of individuals found at the three stations was 33, where ST II dominated with 12 with an average of 3 individuals per depth. Distribution of individuals per depth at ST II was highest at a depth of 10 m with 4 individuals, followed by a depth of 5 and 15 m each with 3 individuals, a depth of 25 m was 1 individual, and no individual was found at 20 m depth. Substrate type at a depth of 10 m was dominated by coral and sandy fractures that could support well the growth and development of red algae.  Alga merah (Rhodophyta) merupakan tumbuhan tingkat rendah yang umumnya tumbuh melekat pada substrat tertentu seperti pada karang, lumpur, pasir, batu dan benda keras lainnya. Salah satu alga yang penting untuk diteliti adalah alga merah (Rhodophyta). Jenis alga ini mengambil nutrisi dari substrat secara difusi melalui dinding thallus-nya sedangkan habitatnya adalah perairan jernih yang mempunyai substrat dasar batu karang, batuan vulkanik dan benda-benda yang bersifat massive yang berada di dasar perairan. Alga merah dapat ditemukan pada daerah intertidal, subtidal sampai daerah tubir dengan ombak besar dan arus deras serta di hutan mangrove. Penelitian ini bertujuan untuk mengetahui diversitas dan pola sebaran serta asosiasi alga merah pada ekosistem lamun dan terumbu karang pesisir Pulau Ternate. Metode yang digunakan pada penelitian ini adalah metode deskriptif dengan pengambilan sampel secara line transek kuadrat (1x1 meter). Lokasi pengambilan sampel dibedakan menjadi tiga stasiun. Data dianalisis secara deskriptif dan jumlah alga merah (Rhodophyta) yang ditemukan pada setiap stasiun di tuangkan dalam peta distribusi berdasarkan data kedalaman serta indeks kepadatannya.  Hasil penelitian menunjukkan bahwa total individu yang ditemukan pada ketiga stasiun adalah sebanyak 33, dimana pada ST II mendominasi dengan jumlah 12 dengan rata-rata perkedalaman adalah 3 individu. Sebaran individu perkedalaman ST II terbanyak pada kedalaman 10 m sebanyak 4 individu, diikuti kedalaman 5 dan 15 m masing-masing adalah 3 individu, kedalaman 25 m sebanyak 1 individu, sedangkan pada kedalaman 20 m tidak ditemukan. Tipe pada kedalam 10 m didominasi oleh patahan karang dan berpasir dimana pada kondisi substrat tersebut dapat mendukung pertumbuhan dan perkembangan alga merah.

Development of the “Digihet” Multimedia Education Program to Improve Health Quality in the Setara Community Group

The digital divide and low health quality are challenges faced by the Setara South Sempaja community group. The impact of flooding is a health problem frequently experienced by this community group. The Technology and Health Education Program (Digihet) is designed to address this issue by providing education on the use of digital technology and clean and healthy living patterns to vulnerable groups affected by health problems. This study aims to develop and evaluate the effectiveness of the Digihet program in improving digital literacy, specifically in clean and healthy living patterns, and the quality of life of the community. The Digihet program is developed using multimedia development techniques, starting from the concept design stage to distribution. The Digihet program teaches about 10 clean and healthy living skills for households, including childbirth assisted by healthcare professionals, exclusive breastfeeding for babies, weighing babies and toddlers, using clean water, washing hands with clean water and soap, using healthy latrines, eradicating mosquito larvae at home, eating fruits and vegetables every day, engaging in physical activity every day, and not smoking indoors. Data were collected through beta testing, and the research results showed that the Digihet program is effective in increasing digital literacy in forming clean and healthy living patterns. The results of this study are expected to serve as a basis for developing multimedia health education programs and contribute to enhancing the understanding of the relationship between digital literacy, public health, and information technology in the context of household health quality
