METHODS: Sixty NAFLD patients (32 males, 28 females; age: 49.7±8.7 years; BMI: 31.1±3.3 kg/m2) were randomized into HIIT, aerobic training, and control cohorts. The HIIT cohort performed 4-minute high-intensity intervals at 85-95% of peak heart rate, interspersed with 3-minute active recovery at 60-70% of peak heart rate for 30-40 minutes per session. The aerobic training cohort performed continuous exercise at 60-70% of peak heart rate for 45-60 minutes per session. Both intervention cohorts underwent 12 weeks of supervised training, thrice weekly. Before and after the intervention, assessments included cardiorespiratory fitness, muscular strength, flexibility, lipid profile, liver enzymes, inflammatory markers, insulin sensitivity, and oxidative stress markers.
RESULTS: Compared to controls, both exercise cohorts showed significant improvements in cardiorespiratory fitness, muscular strength, and flexibility. However, HIIT elicited superior enhancements in cardiorespiratory fitness and muscular strength. Biochemically, both exercise cohorts exhibited reductions in triglycerides, low-density lipoprotein (LDL) cholesterol, liver enzymes (alanine aminotransferase [ALT], aspartate aminotransferase [AST]), inflammatory markers (C-reactive protein [CRP], interleukin-6 [IL-6]), insulin resistance (homeostatic model assessment of insulin resistance [HOMA-IR]), and oxidative stress markers (malondialdehyde [MDA], protein carbonyl). Notably, HIIT yielded more substantial improvements in these parameters.
CONCLUSIONS: HIIT and traditional aerobic training are effective in improving physical fitness and ameliorating biochemical indicators in NAFLD patients. Notably, HIIT appears to be more advantageous in enhancing cardiorespiratory fitness, muscular strength, and metabolic, inflammatory, and oxidative stress profiles, suggesting its potential as a time-efficient and effective exercise modality for managing NAFLD.
MATERIALS AND METHODS: Six participants with SCI were recruited for a pilot study to investigate the exercise intensity of selected exergames (Move Tennis, Move Boxing, and Move Gladiator Duel) for the potential to improve health. Issues relating to exergaming for individuals with SCI were identified, and a Move Kayaking exergame was conceived using relevant design processes in an iterative manner. These processes included the following: participant needs and requirements, system requirements (hardware), system architecture (physical and operational views), and integration and verification of the finished system. Emphasis was given to operational and physical designs of the Move Kayaking exergame.
RESULTS: Move Boxing, Move Gladiator Duel, and Move Kayaking achieved moderate intensity exercise, while Move Tennis only achieved exercise of low intensity based on participants' metabolic equivalent. However, all four exergames achieved at least moderate intensity based on individuals' ratings of perceived exertion (RPE).
CONCLUSION: The intensity classification while playing Move Boxing, Move Tennis, Move Gladiator Duel, and Move Kayaking, using RPE, reported adequate exercise intensities prescribed by exercise guidelines.
METHOD: Between November 2009 and July 2010, outpatients from 45 countries who met the criteria for stable CAD were recruited into the registry. Baseline characteristics were documented at enrolment, and patients were reassessed during their annual visits over a five-year follow-up period. Key outcomes measured were sudden death and cardiovascular (CV) death, non-CV death and CV morbidity.
RESULTS: At baseline, 33,283 patients were available for analysis within the registry; 380 and 27 were Malaysians and Bruneians, respectively. The mean ages of Malaysian/Bruneian patients and the rest of the world (RoW) were 57.83 ±9.98 years and 64.23 ± 10.46 years, respectively (p<0.001). The median body mass index values were 26.6 (24.4-29.6) kg/m2 and 27.3 (24.8-30.3) kg/m2, respectively (p=0.014). Malaysian/Bruneian patients had lower rates of myocardial infarction (54.55% versus 59.76%, p=0.033) and higher rates of diabetes (43.24% versus 28.99%, p<0.001) and dyslipidaemia (90.42% versus 74.66%, p<0.001) compared with the RoW. Measured clinical outcomes in Malaysian and Bruneian patients at 2-years follow-up were low and generally comparable to the RoW.
CONCLUSION: Malaysian/Bruneian patients with stable CAD tend to be younger with poorer diabetic control compared with the RoW. However, they had similar outcomes as the main registry following two years of treatment.
Case presentation: A 29-year-old female with incomplete paraplegia secondary to tuberculosis (TB) spondylodiscitis presented with asymptomatic sinus tachycardia. The related medical conditions, including anaemia, acute coronary syndrome, hyperthyroidism and other infective causes had been ruled out. Deep venous thrombosis was not on the list of differentials as she showed improvements in neurological and mobility functions with no clinical signs of calf pain or swelling. She had moderate risk of acute PE based on Wells' criteria with positive D-dimer testing and computed tomography pulmonary angiography (CTPA) showing thrombus formation in the left-ascending pulmonary artery.
Discussion: Acute PE may present solely with asymptomatic sinus tachycardia in TB spondylodiscitis. This caveat should provide a high index of suspicion to prevent delay in diagnosis and prevention of more sinister complications. Early stratification based on Wells' criteria for a possible diagnosis of acute PE is proven to be a useful approach in conjunction with clinical features.
METHOD: A single-blind RCT was conducted among 30 randomized patients with dental phobia to either VRET or informational pamphlet (IP) condition. Primary outcome anxiety measures (VAS-A, MDAS and DFS) were evaluated at baseline, pre- and post-intervention, 1-week, 3-months and 6-months follow-up. Secondary outcome measures assessed were pre-post behavioral avoidance, temporal variations of heart rate and VR-experience during and post-VRET, and dental treatment acceptance in both conditions at 6-month follow-up.
RESULTS: Intention to treat analysis, using a repeated measures MANOVA, revealed a multivariate interaction effect between time and condition (p = 0.015) for all primary outcome measures (all ps
CASE PRESENTATION: A 59-year-old man presented with the complaint of recurrent dizziness associated with meals. A 24-h ambulatory ECG recording confirmed an episode of p-wave asystole at the time of food intake. Oesophagogastroduodenoscopy with balloon inflation in the mid to lower oesophagus resulted in a 5.6 s sinus pause. The patient's symptoms resolved completely following insertion of a permanent dual chamber pacemaker.
CONCLUSIONS: Swallow syncope is extremely rare, but still needs to be considered during diagnostic workup. It is commonly associated with gastro-intestinal disease. Permanent pacemaker implantation is the first line treatment.
