Age-associated cerebrovascular disease impacts brain tissue integrity, but other factors, including normal variation in blood markers of systemic health, may also influence the structural integrity of the brain. This cross-sectional study included 139 individuals between 40 to 86 years old who were physically healthy and cognitively intact. Eleven markers (total-cholesterol, high-density lipoprotein, low-density lipoprotein, triglyceride, insulin, fasting glucose, glycated hemoglobin, creatinine, blood urea nitrogen, albumin, total protein) and five derived indicators (estimated glomerular filtration rate, creatinine clearance rate, insulin-resistance, average glucose, and cholesterol/high-density lipoprotein ratio) were obtained from blood sampling. Diffusion tensor imaging was used to evaluate white matter tissue health. Blood markers were clustered into five factors. The first factor (defined as insulin/high-density lipoprotein factor) was associated with markers of integrity in the deep white matter and projection fiber systems, while the third factor (defined as kidney function factor) was associated with different markers of integrity in the periventricular and watershed white matter regions. Differential segregated associations for insulin and high-density lipoprotein levels and serum markers of kidney function may provide information about distinct mechanisms of brain changes across the lifespan. These results emphasize the need to determine whether therapeutic modulation of systemic health and organ function may prevent decline in brain structural integrity.

Latar belakang: Gangguan pendengaran akibat bising (GPAB) adalah komplikasi yang palingumum disebabkan oleh paparan terhadap bising, meskipun ada beberapa komplikasi lain yang bisadisebabkan oleh paparan bising. Komplikasi metabolik dari paparan terhadap bising telah dievaluasi olehberbagai penelitian.Tujuan: Meneliti hubungan antara GPAB dengan kadar profil lipid pada pekerja yangterpapar bising di lingkungan kerja.Metode: Penelitian ini bersifat deskriptif analitik dengan desain crosssectional study. Data diperoleh melalui proses wawancara, pemeriksaan audiometri, dan pemeriksaankadar profil lipid.Hasil: Rerata intensitas kebisingan bagian proses 98 dB, dan non-proses berkisar 46-98 dB. Berdasarkan hasil pemeriksaan audiometri terhadap 50 pekerja yang memenuhi kriteria inklusidan eksklusi, didapatkan 26 orang (52%) dengan GPAB tuli sensorineural dan 24 orang (48%) tidakmengalami GPAB. Kami menemukan hubungan signifikan antara paparan bising pada pekerja denganpeningkatan kadar trigliserida (TG), total kolesterol (TC), low-density lipoprotein (LDL), dan penurunankadar high-density lipoprotein (HDL) (p<0,05). Terdapat hubungan antara kadar TG yang tinggi terhadapterjadinya GPAB pada pekerja yang terpapar bising dengan intensitas >85 dB (p<0,05) dan tidak dijumpaihubungan peningkatan kadar TC, LDL, dan penurunan kadar HDL terhadap terjadinya GPAB (p>0,05).Kesimpulan: Pada penelitian ini, ada hubungan antara hiperlipidemia dengan GPAB. Pekerja denganhipertrigliseridemia yang tepapar bising >85 dB berisiko lebih besar menderita GPAB. Kata kunci: Kebisingan, GPAB, profil lipid ABSTRACTBackground: Noise induced hearing loss (NIHL) is the most common complication that causedby noise exposure, although there are other complications as a result of noise exposure. Metaboliccomplications from noise exposure have been evaluated in various studies. Purpose: To examine therelationship between NIHL with lipid profile in workers who are exposed to noise in workplace. Methods:The study design was analytic descriptive with cross-sectional study. Data collection was done throughinterviews, audiometry screening, and lipid profile examinations. Results: The average intensity in processsection was 98 dB, and in non-process section ranged between 46-98 dB. The results of audiometricexamination of the 50 workers who met the inclusion criteria, were 26 persons (52%) with sensorineuralNIHL and 24 persons (48%) did not experience NIHL. We found a significant association between noiseexposure among workers with elevated levels of triglyceride (TG), total cholesterol (TC), low-densitylipoprotein (LDL), and decreased high-density lipoprotein (HDL) levels (p<0,05). There was highcorrelation beween TG levels with the NIHL among workers who are exposed to noise >85 dB (p<0,05),and no correlation between elevated levels of TC, LDL and decreased HDL levels with NIHL (p>0,05).Conclusion: We found a significant relationship between hyperlipidemia and NIHL. Workers withhypertriglyceridemia had greater risk of suffering NIHL when exposed to noise >85 dB in the workplace. Keywords: Noise, NIHL, lipid profile

Objective: In contrast to low-density lipoprotein cholesterol, and high density lipoprotein cholesterol, which are well-established independent risk factors for cardiovascular disease, the importance of triglycerides remains controversial. In this study, we evaluated the associations between triglycerides and endothelial function in the general population. Methods and Results: We enrolled 4,908 subjects (3842 men and 1066 women; mean age, 48±12 years) who were enrolled in FMD-Japan registry. And, we investigated cross-sectional associations between triglycerides and endothelial function by measurement of flow-mediated vasodilation (FMD). The triglycerides levels were negatively associated with FMD (r=-0.10, P<0.001). Subjects were divided into six groups on the basis of the triglycerides level. FMD was significantly decreased with an increase in the triglycerides level (≤63 mg/dL, 7.0±3.5%; 64 to 83 mg/dL, 6.3±3.5%; 84 to 105 mg/dL, 6.0±3.1%; 106 to 131 mg/dL, 5.8±3.2%; 132 to 179 mg/dL, 5.7±3.1%; ≥180 mg/dL, 5.5±3.0%; P for trend<0.001). After adjustment for age, sex, cardiovascular risk factors including high density lipoprotein cholesterol, high triglycerides level groups independently remained associated with low quartile of FMD using the triglycerides ≤63 mg/dL group as the reference (Table). Conclusions: These findings supported an independent association between triglycerides and cardiovascular disease.

ABSTRACTBackground:Research shows that lipid levels may be associated with cognitive function, particularly among women. We aimed to examine total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), high-density lipoprotein (HDL), and HDL/LDL ratio in relation to cognitive performance, measured with six well-established cognitive domains and a composite cognitive score (CCS).Methods:In this cross-sectional study, biomarkers and neuropsychological assessment were available for 141 adults with MMSE scores ≥ 24 (mean age = 69 years, 47% female, mean education = 14.4 years) attending a neuropsychological evaluation. Ordinary least squares regressions were adjusted for age, gender, education, and depressive symptoms in Model 1 and also for apolipoprotein E4 (APOE4) status in Model 2.Results:High-density lipoprotein cholesterol (HDL-C) was associated with better CCS (β = 0.24; p = 0.014). This association was significant among women (β = 0.30; p = 0.026) and not among men (β = 0.20; p = 0.124). HDL-C was also related to attention/working memory (β = 0.24; p = 0.021), again only among women (β = 0.37; p = 0.012) and not men (β = 0.15; p = 0.271). Adjusting for APOE4 yielded significance for high HDL-C and CCS (β = 0.24; p = 0.022).Conclusions:HDL-C was the main lipoprotein affecting cognitive function, with results somewhat more pronounced among women. Research should investigate the possibility of finding ways to boost HDL-C levels to potentially promote cognitive function.

Stroke iskemik merupakan tipe stroke yang paling sering terjadi pada serangan berulang. Subtipe yang paling sering terjadi adalah aterosklerosis arteri besar yang menyebabkan oklusi arteri pada otak. Abnormalitas lipid plasma merupakan penyebab utama terjadinya aterosklerosis. Rasio lipid dapat menginformasikan risiko aterosklerosis yang sulit diukur dengan pemeriksaan rutin dan peningkatan rasio lipid menggambarkan ketidakseimbangan antara fraksi lipid aterogenik dan antiaterogenik. Penelitian ini bertujuan untuk mengetahui gambaran profil lipid dan rasio lipid pada pasien stroke iskemik berulang di RSUD Abdul Wahab Sjahranie Samarinda. Penelitian ini bersifat deskriptif dengan desain studi cross sectional. Pengambilan sampel secara purposive sampling pada pasien stroke iskemik yang mempunyai riwayat stroke iskemik sebelumnya sebanyak 71 sampel. Pengambilan data profil lipid menggunakan data sekunder dari rekam medik dan rasio lipid didasarkan pada perbandingan kolesterol total (K-Total)/kolesterol high density lipoprotein (K-HDL), kolesterol low density lipoprotein (K-LDL)/K-HDL, dan trigliserida (TG)/K-HDL. Pada penelitian ini didapatkan hasil pasien stroke iskemik berulang paling banyak dengan K-Total yang optimal sebesar 49,3%, K-LDL mendekati optimal 42,2%, K-HDL rendah 71,8%, TG optimal 62,0%, rasio K-Total/K-HDL di atas nilai risiko 76,1%, rasio K-LDL/K-HDL di atas nilai risiko 63,4%, dan rasio TG/K-HDL di atas nilai risiko 52,1%. Berdasarkan hasil ini dapat disimpulkan bahwa profil lipid pasien stroke iskemik berulang di RSUD Abdul Wahab Sjahranie Samarinda paling banyak ditemukan dengan kadar K-Total dan TG yang optimal, K-LDL yang mendekati optimal, dan kadar K-HDL yang rendah. Rasio lipid yang terdiri dari rasio K-Total/K-HDL, rasio K-LDL/K-HDL dan rasio TG/K-HDL masing-masing ditemukan paling banyak dengan rasio di atas nilai risiko.
