Osteoartritis (OA) lutut merupakan masalah kesehatan masyarakat utama yang mengakibatkan nyeri dan disabilitas. Sampai saat ini masih belum jelas diketahui dampak penyakit OA lutut dilihat dari derajat nyeri dan klasifikasi radiologik OA dengan kualitas hidup pasien OA lutut. Tujuan penelitian ini adalah mengetahui hubungan derajat nyeri dan klasifikasi radiologik OA dengan kualitas hidup pasien OA lutut. Penelitian ini adalah studi analitik dengan pendekatan cross sectional. Sebanyak 85 pasien OA telah dipilih secara consecutive dan dinilai kualitas hidupnya yang terdiri atas delapan komponen menggunakan kuesioner SF-36, derajat nyerinya menggunakan numeric rating scale (NRS), serta secara radiologik berdasar atas klasifikasi Kellgren-Lawrence (KL). Penelitian ini dilakukan di RS Al-Islam Bandung selama periode April–Juli 2018. Data dianalisis dengan SPSS melalui Uji Kruskal-Wallis. Dari hasil penelitian didapatkan mayoritas pasien OA lutut mengalami derajat nyeri sedang (50%) termasuk dalam klasifikasi radiologik OA moderat (43%) dan skor kualitas hidup 548 (265,63–728,5). Penelitian ini menunjukkan hubungan bermakna antara derajat nyeri dan kualitas hidup pada aspek nyeri dan vitalitas (p=0,000 dan 0,005) serta hubungan klasifikasi radiologik OA dengan kualitas hidup aspek fungsi sosial (p=0,027). Disimpulkan bahwa terdapat hubungan derajat nyeri dengan kualitas hidup pada aspek nyeri dan vitalitas serta hubungan klasifikasi radiologik OA dengan kualitas hidup pada aspek fungsi sosial.

Pain, joint stiffness, and difficulty performing activities like rising from sitting to standing are signs and symptoms of knee osteoarthritis (OA). These conditions are risk factors for limited mobility and lower quality of life. Knee OA is closely associated with age, women, obesity, and other characteristics. The study's objectives were to determine the correlation of knee OA patients' characteristics with functional mobility using the 30-second sit-to-stand test (30STS) and the correlation of functional mobility with quality of life using the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index. The research method was descriptive-analytic cross-sectional using medical records of 73 knee OA patients at the Medical Rehabilitation Clinic at Soreang Hospital, Muhammadiyah Hospital, Al Islam Hospital, Al-Ihsan Regional General Hospital West Java Province, Bandung, from March until August 2021. Patients' characteristics such as age (p=0.02), onset (p=0.01), OA grade (p=0,03), and knee deformity (p=0.04 ) have a negative correlation with functional mobility based on 30STS as well as functional mobility had a negative correlation with various aspects of quality of life, such as pain (p=0.03), stiffness (p=0.02), and functional limitation (p=0.00) subscales based on WOMAC index. Age, the onset of disease, OA grade, and knee deformity significantly correlate to functional immobility. Based on the WOMAC index, functional immobility correlates with the patient's quality of life.

Background: The medical student is a part of education that has a pivotal role in contributing to the teaching-learning process. Assessing the learning process by student perception can give valuable input to predict academic achievement. This study aims to identify the student’s perspective regarding teaching-learning behaviour and which factor most influences academic achievement. Methods: A total of 443 medical students of the preclinical phase were selected to participate in this study. Design of the study comprised three single-groups time sequences with the observational approach. This study is divided into three phases: item construction by conducting exploratory factor analysis (EFA), validation through confirmatory factor analysis (CFA), and true surveys. Sample size calculation employed formulation of subject to item ratio for EFA and CFA; true survey utilized the estimate proportion population. Using regression linear, we determine the most influential factor to academic performance. Results: Results were summarized following two factors that influencing academic performance, namely learning experience (p value=0.013, r=0.041) and exam effectiveness (p value=0.041, r=0.028). Our work highlights the lecturer capacity and integrated module have contributed the academic success (79.46% and 77.80%). Conclusions: Our finding has novelty in which contribute the knowledge regarding exam significance on medicine. Meanwhile, related to the learning experience domain is increasingly proving an essential factor to achieve academic performance. The major strength of this study is the systematic manner in which it was conducted.

Abstract. Globally, there were 568.4 million common cases of low back pain in 2019 and the incidence was higher in students at the Faculty of Medicine with relatively tight class hours. This study aims to determine the relationship between prolonged sitting and the incidence of low back pain in third year students of the Faculty of Medicine Unisba in 2022. This type of research is quantitative with an analytic observational method and a cross sectional approach design. The instrument used is a questionnaire. A sample of 134 third year students at the Faculty of Medicine, Unisba in 2022, used the total sampling technique. The data analysis used was univariate and chi square test for bivariate analysis. Most of third year students of the Faculty of Medicine Unisba in 2022 experience lower back pain. It was found that there was a significant relationship between sitting duration and complaints of low back pain in 3rd year Unisba Medical Faculty students in 2022 with p-value = 0.034 (p <0.05). Sitting for a long time causes an increase in muscle contractions which produce waste products in the form of lactic acid and then cause pain in the lower back. It was concluded that prolonged sitting was associated with lower back pain. Keywords: Prolonged Sitting,  Medical Student, Low Back pain Abstrak. Secara global, terdapat 568,4 juta kasus umum nyeri punggung bawah pada tahun 2019 dan insidensi lebih tinggi pada mahasiswa Fakultas Kedokteran dengan jam kuliah yang terbilang padat. Penelitian ini bertujuan untuk mengetahui hubungan lama duduk dengan kejadian nyeri punggung bawah pada mahasiswa Fakultas Kedokteran Unisba tingkat 3tahun 2022. Jenis penelitian ini adalah kuantitatif dengan metode observasional analitik dan rancangan pendekatan cross sectional. Instrumen yang digunakan berupa kuesioner. Sampel sebanyak 134 mahasiswa tingkat 3 Fakultas Kedokteran Unisba tahun 2022 dengan teknik total sampling. Analisis data yang digunakan adalah univariat dan uji chi square untuk analisis bivariat. Sebagian besar mahasiswa Fakultas Kedokteran Unisba tingkat 3 tahun 2022 mengalami nyeri punggung bawah. Didapatkan bahwa terdapat hubungan bermakna antara lama duduk dengan keluhan nyeri punggung bawah pada mahasiswa Fakultas Kedokteran Unisba tingkat 3 tahun 2022 dengan p-value= 0.034 (p < 0,05). Hal tersebut karena duduk dalam waktu lama menyebabkan peningkatan kontraksi otot yang menghasilkan produk sisa berupa asam laktat dan kemudian mengakibatkan nyeri pada punggung bawah. Disimpulkan lama duduk berhubungan dengan nyeri punggung bawah.   Kata Kunci: Duduk Lama, Mahasiswa Fakultas Kedokteran, Nyeri Punggung Bawah
