This study was conducted to evaluate the discomfort level of students from the Polytechnic Kuching Sarawak while they were sitting on chairs. Polytechnic Kuching students (n=500) completed a set of questionnaires utilizing a survey form which showed the body chart discomfort using Borg’s CR-10 Scale. The students was asked to identify body areas experiencing discomfort and to rate this discomfort using score rating groups (0 to 5) where score 0-1.99 = No discomfort (1), score 2.00-3.99 = Discomfort (2) and score 4.00-5.00 = Very uncomfortable (3). The evaluation of seating discomfort levels showed acceptable levels for the students and possible outstanding problems. Students were asked to rank over an order 10 statements about comfort and choose three responses which gave the most consistent equal interval scale. The results showed that the main response of discomfort indicated the students felt cramped, stiff, numb, sore and tender muscle, unbearable pain, barely comfortable and uncomfortable. This project was identified to evaluate the comfort level for classrooms chairs of polytechnic students. Overall, there was a significant discomfort level for the students whilst sitting on chairs and a possible solution put forward is to design a new type of classroom chair made of natural fibre reinforced composite.

PURPOSE: To evaluate osseous changes of temporomandibular joint (TMJ) in patients with rheumatoid arthritis (RA) using cone-beam computed tomography (CBCT) and to correlate the imaging findings with the severity of TMJ dysfunction, clinical findings, and laboratory findings. MATERIALS AND METHODS: This study consisted of 28 subjects, including 14 RA patients and 14 controls, who were scheduled to undergo CBCT imaging for the diagnosis of a complaint not related to or affecting the TMJ. The Fonseca's questionnaire was used to assess the severity of TMJ dysfunction. Rheumatoid factor (RF) and the erythrocyte sedimentation rate (ESR) were assessed in the RA patients. CBCT was then performed in all subjects and osseous TMJ abnormalities were assessed. RESULTS: According to the Fonseca's questionnaire, 14.3% of the patients had no TMJ dysfunction, while 50%, 21.4%, and 14.3% had mild, moderate, and severe dysfunction, respectively. RF was positive in 64.3% of patients, and the ESR level was high in 100%. Imaging findings revealed a statistically significantly higher prevalence of erosion (85.7%), flattening (89.3%), osteophyte formation (32.1%), subchondral cyst (32.1%), sclerosis (64.3%), and condylar irregularities (28.6%) in the RA patients than in the controls. No correlations were found between CBCT findings and the clinical findings, the severity of TMJ dysfunction, disease duration, or laboratory results. CONCLUSION: RA patients might show extensive osseous abnormalities with no/mild clinical signs or symptoms of TMJ dysfunction that necessitate TMJ imaging for these patients. CBCT is a valuable and efficient modality that can assess osseous TMJ changes in RA patients.

This systematic review and meta-analysis aimed to examine the effect of the antioxidant alpha-lipoic acid (ALA) on various cardiometabolic risk factors and hormonal parameters in patients with polycystic ovary syndrome (PCOS). We searched PubMed, EMBASE, SCOPUS, Cochrane Library, and Web of Science databases without language restrictions until May 2023 to find randomized controlled trials (RCTs) that assessed the impact of ALA supplementation on anthropometric, glycemic, lipid, oxidative stress, and hormonal parameters in women with PCOS. Outcomes were summarized using the standardized mean difference (SMD) and 95% confidence interval (CI) in a random-effects model. An I2 statistic of >60% established significant between-study heterogeneity. The overall certainty of the evidence for each outcome was determined using the grading of recommendations, assessment, development, and evaluations system. Seven RCTs met the inclusion criteria. The ALA group had significant reductions in fasting blood sugar (fasting blood sugar (FBS), n=7 RCTs, SMD, -0.60; 95% CI, -1.10 to -0.10; I2=63.54%, moderate certainty of evidence) and homeostatic model assessment for insulin resistance (homeostatic model assessment of insulin resistance (HOMA-IR), n=4 RCTs, SMD, -2.03; 95% CI, -3.85 to -0.20; I2=96.32%, low certainty of evidence) compared with the control group. However, significant differences were observed between the groups in body mass index, insulin, estrogen, follicle-stimulating hormone, luteinizing hormone, testosterone, low-density lipoprotein, highdensity lipoprotein, triglyceride, total cholesterol, malondialdehyde, or total antioxidant capacity profiles. ALA supplementation improves FBS and HOMA-IR levels in women with PCOS. ALA consumption is an effective complementary therapy for the management of women with PCOS.

Objectives: This study determined the baseline hormonal levels of the hypothalamic-pituitary-adrenal axis and their associated factors in noncritically ill hospitalized patients with coronavirus disease 2019 (COVID-19). Methodology: This cross-sectional observational study was carried out in 91 noncritical RT-PCR-confirmed COVID-19 patients (18-65 years) recruited consecutively from the COVID unit, of two tertiary care hospitals over a period of six months. After screening for exclusion criteria relevant history and physical examinations were done, and blood was drawn between 07:00 am to 09:00 am in a fasting state to measure serum cortisol and plasma adrenocorticotropic hormone (ACTH) by chemiluminescent microparticle immunoassay. Result: Of 91 patients, 54, 26, and 11 had mild, moderate, and severe disease respectively. Median values of serum cortisol (p=0.057) and plasma ACTH (p=0.910) were statistically similar among the severity groups. Considering cortisol cut-off of 276 nmol/L (<10 μg/dL), the highest percent of adrenal insufficiency was present in severe (27.3%), followed by mild (25.9%) and least in moderate (3.8%) COVID-19 cases. Using the cortisol/ACTH ratio >15, only 6.6% had enough reserve. Conclusions The adrenocortical response was compromised in a significant percentage of noncritically ill hospitalized patients with COVID-19, which is unrelated to infection severity, with greater percentages present in severely infected cases.
