Abstract

Adolescence is a transitional period characterized by physical, mental, and social changes that often encourage risk taking behaviors, including sexual activity. According to the World Health Organization (WHO), adolescents are individuals aged 10–19 years. In Nusa Tenggara Barat (NTB), the prevalence of early marriage reaches 58.1%, which is higher than the national average of 34.0%, and there is a growing trend of premarital sexual activity. These behaviors can lead to unintended pregnancies, abortions, sexually transmitted infections (STIs), and psychosocial problems. This study aims to describe the phenomenon of risky sexual behavior among adolescents in NTB, identify the contributing factors, and discuss its impacts and possible preventive strategies. This research employed a literature review method by collecting, reviewing, and synthesizing scientific articles and relevant reports. The findings indicate that risky sexual behavior is influenced by parenting style, peer pressure, pornography exposure, personality traits, and limited knowledge of sexual and reproductive health, resulting in early marriage, unintended pregnancies, abortions, and an increased risk of STIs and HIV/AIDS. In conclusion, risky sexual behavior among adolescents in NTB remains a significant public health concern. Strengthening comprehensive sexual education, enhancing parental communication, and expanding access to youth friendly reproductive health services are recommended to reduce its prevalence and negative impacts.

Abstract

Cognitive impairment can occur due to factors that affect the structural and functional integrity of brain areas that specifically play a role in each cognitive domain. Severe cognitive impairment causes morbidity and mortality. One condition that can lead to complications such as a cognitive impairment is Decompression Sickness (DCS). DCS is an important risk for divers and manifestations of cognitive impairment need to be recognized earlier to prevent progression to a more severe stage. The literature used was collected from the Google Scholar, ScienceDirect, and PubMed databases with restrictions: publication year 2015-2025, Indonesian or English languages, and research with human subjects. The results of the literature review indicate that the pathophysiology of cognitive impairment after onset of DCS is still not clearly understood. The principles that are understood so far include the impact of nitrogen gas bubble circulation in cerebral arteries, extensive brain ischemia, white matter damage, and hyperbaric pressure administration can simultaneously improve cognitive function in patients. It can be concluded that neurological symptoms in DCS can develop into severe cognitive impairment if not recognized and treated immediately. The underlying relationship is mainly related to the impact of nitrogen gas embolism, cerebral ischemia, and extensive damage to cognitive areas of the brain.

Abstract

Von Willebrand disease (vWD) is the most common hereditary bleeding disorder caused by a deficiency or dysfunction of von Willebrand factor (vWF), a key protein involved in both primary and secondary hemostasis. This study aims to review the current understanding of diagnosis, classification, and management strategies for vWD based on disease type and severity. A literature review approach was employed to analyze recent findings on the pathophysiology, diagnostic criteria, and therapeutic advances related to vWD. Accurate diagnosis remains crucial, as treatment must be tailored to the specific subtype and clinical severity. Current management focuses on increasing circulating levels of vWF and factor VIII through local hemostatic measures, antifibrinolytic agents such as tranexamic acid, desmopressin (DDAVP) for responsive patients, and vWF/factor VIII concentrates for severe cases or DDAVP contraindications. A multidisciplinary perioperative management plan is essential to minimize bleeding risks during surgical or invasive procedures. Despite advances in therapy, challenges persist in early detection and individualized treatment optimization. Comprehensive evaluation, improved clinical awareness, and collaborative care among healthcare providers are vital to enhancing patient outcomes and quality of life.
