    This paper aims to determine acute responses of standardized resistance training load on cardio-respiratory variables in recreationally active participants. The methodology involved twelve recreationally active males with an age of 23.5 (± 4.07) years, a mass of 70.5 (± 7.84 kg), a height of 1.69 (± 0.06 m), and a body mass index of 24.8 (± 2.14) kg/m2). The participants performed an exercise protocol that comprises five exercises on a standardized load. Each exercise was performed in a duration of 60 seconds with uncontrolled lifting velocity. Cardio-respiratory responses were measured using a portable metabolic system analyzer during the exercises. A wrist digital blood pressure monitor was used to determine pre- and postprotocol blood pressure responses. Based on the results, pre- and postprotocol systolic (p=0.744) and diastolic (p=0.758) blood pressure indicated no significant responses. However, significant differences were observed in pre- and post-heart rate responses (p=0.000). Peak cardio-respiratory responses recorded during the protocol were 30.2 (± 4.02) ml/Kg/min for oxygen consumption, 138 (± 61.9) bpm for heart rate, and 633 (± 71.2) kcal for energy expenditure (estimated per hour). On average, the Metabolic Equivalent of Task (MET) was recorded at a value of 8.62 (± 1.19). For a short duration standardized load circuit training exercise protocol, cardio respiratory responses were similar to other protocols. The metabolic cost of the predefined exercises was nearly half of the recommended energy expenditure through exercise per week. The prescribed protocol was comparable with other exercise protocols for cardiorespiratory variables. The single set protocol used was efficient in terms of caloric expenditure, and was less strenuous over similar exercise duration. Furthermore, the prescribed protocol is applicable and beneficial for active and healthy individuals.

    Anaphylaxis in the operating room although infrequent can be potentially fatal. The diagnosis of perioperative anaphylaxis is complex due to a multitude of factors. Firstly, patients under anesthesia cannot verbalize their complaints, the anesthetic agents themselves can alter vital parameters (e.g. heart rate and blood pressure) and cutaneous signs in a completely draped patient may be missed. Secondly, the differential diagnosis of intraoperative anaphylaxis is wide. Conditions such as asthma exacerbation, arrhythmia, hemorrhage, angioedema, mastocytosis, acute myocardial infarction, drug overdose, pericardial tamponade, pulmonary edema, pulmonary embolus, sepsis, tension pneumothorax, vasovagal reaction, venous air embolism, laryngospasm, blood transfusion reaction and malignant hyperthermia need to be considered. Thirdly, the diagnostic workup is challenging due to the multiple medications administered and other exposures encountered such as latex and chlorhexidene. However, through a timely allergy consultation and a systematic approach, identification of the culprit agent and safe alternatives can be established to prevent future occurrences as illustrated in the case below.

    A cross sectional study to determine the exposure of heat and its biological effects on the workers in a plastic factory located in the Shah Alam Industrial Estate, Selangor, Malaysia. Forty five respondents from the polymer section in the factory were selected as the respondents. Variables measured were the environmental temperature (WBGTin), air velocity, relative humidity, body temperature, average heart and recovery heart rate. QUESTEMP°34 Area Heat Stress Monitor was used to measure the environmental temperature in °C (WBGTin) and relative humidity (%). Velocicheck Model TSI 8830 was used to measure the air velocity in meter per second (m/s) while the OMRON Blood Pressure Monitor Model T3, was used to measure average heart rate and recovery heart rate. Body temperature (°C) was measured by the Instant Ear Thermometer-OMRON Gentle Temperature Model MC509. Interviews using questionnaires were used to determine respondents’ socioeconomic background, previous risk factors on heat exposure and other information related to heat stress. Results showed that the mean environmental temperature for the exposed group was 28.75°C, the mean air velocity was 0.15 m/s and the mean relative humidity was 58.1%. These production workers were exposed occasionally to heat when loading plastic powder into the molds as well as demolding the finished plastic products from the molds. The average time of monitoring was 2 hours for intermittent exposure and 8 hours duration for overall exposure. Maximum demand for work load was measured 1 minute after work activities were stopped at the demolding section. There was a significant difference between body temperature and average heart rate before work, after 2 hours of work and after 8 hours of work ( p < 0.001). The mean recovery heart rate after 1 min was 88.0 ± 12.0 beat per min. (bpm), indicating that there is no excessive physiological demand. Body temperature (36.8 ± 0.40°C) and average heart rate after 8 hours (78 ± 12 bpm) indicated a good body control of heat exposure. Five out of six workplaces monitored had temperatures of greater than 28°C (ACGIH TLV). The workers were exposed to moderate heat stress during the study period, however, body temperature and average heart rate measurement did not reach unacceptable level of physiologic strain.

    BACKGROUND: Transaldolase deficiency (TALDO-D) is a rare autosomal recessive inborn error of the pentose phosphate pathway. Since its first description in 2001, several case reports have been published, but there has been no comprehensive overview of phenotype, genotype, and phenotype-genotype correlation.

    METHODS: We performed a retrospective questionnaire and literature study of clinical, biochemical, and molecular data of 34 patients from 25 families with proven TALDO-D. In some patients, endocrine abnormalities have been found. To further evaluate these abnormalities, we performed biochemical investigations on blood of 14 patients.

    RESULTS AND CONCLUSIONS: Most patients (n = 22) had an early-onset presentation (prenatally or before 1 month of age); 12 patients had a late-onset presentation (3 months to 9 years). Main presenting symptoms were intrauterine growth restriction, dysmorphic facial features, congenital heart disease, anemia, thrombocytopenia, and hepato(spleno)megaly. An older sib of two affected patients was asymptomatic until the age of 9 years, and only after molecular diagnosis was hepatomegaly noted. In some patients, there was gonadal dysfunction with low levels of testosterone and secondary luteinizing hormone (LH) and follicle-stimulating hormone (FSH) abnormalities later in life. This overview provides information that can be helpful for managing patients and counseling families regarding prognosis. Diagnostic guidelines, possible genotype-phenotype correlations, treatment options, and pathophysiological disease mechanisms are proposed.

    The pathophysiology of systemic inflammatory response syndrome (SIRS) had been described to involve various strong oxidative reactions affecting the status and progress of the patients. Antioxidant therapy had been suggested in many studies involving SIRS management. The objective of this study was to compare the role of vitamin E Tocotrienol and vitamin E Tocopherol combined with vitamin C as antioxidant therapy in the management of critically ill patients diagnosed with SIRS, admitted to the intensive care unit and high dependency wards of Universiti Kebangsaan Malaysia Medical Centre (UKMMC). It was a single blind randomized clinical trial with a total of 72 patients in which 44.4% Malays, 34.7% Chinese, 19.4% Indians and 1.4% others with 59.7% males and 40.3% females were recruited. Patients in TRI E group received Tocotrienol with Vitamin C while TOCO group received Tocopherol with Vitamin C and a control group did not receive any antioxidant. The clinical parameters (heart rate, respiratory rate, systolic blood pressure) showed improvements with significant difference at the end of study (post-intervention) as compared to admission (pre-intervention).Whereas, the sepsis (temperature, PCT, CRP and WBC) and oxidative stress (8-OHdG/Creatinine) parameters showed improvements with significant difference at the end of study (post-intervention) as compared to admission (pre-intervention). The TRI E group showed obvious improvement in clinical, sepsis and oxidative stress parameters, as compared to TOCO and control groups. This study showed that Vitamin E Tocotrienol and Vitamin E Tocopherol in combination with Vitamin C demonstrated significant improvement in the clinical and laboratory parameters during the management of SIRS. Therefore, Vitamin E in combination with Vitamin C had therapeutic benefits in the treatment of critically ill patients with SIRS.

    Thyrotoxicosis is associated with cardiac dysfunction; more commonly, left ventricular dysfunction. However, in recent years, there have been more cases reported on right ventricular dysfunction, often associated with pulmonary hypertension in patients with thyrotoxicosis. Three cases of thyrotoxicosis associated with right ventricular dysfunction were presented. A total of 25 other cases of thyrotoxicosis associated with right ventricular dysfunction published from 1994 to 2017 were reviewed along with the present 3 cases. The mean age was 45 years. Most (82%) of the cases were newly diagnosed thyrotoxicosis. There was a preponderance of female gender (71%) and Graves' disease (86%) as the underlying aetiology. Common presenting features included dyspnoea, fatigue and ankle oedema. Atrial fibrillation was reported in 50% of the cases. The echocardiography for almost all cases revealed dilated right atrial and or ventricular chambers with elevated pulmonary artery pressure. The abnormal echocardiographic parameters were resolved in most cases after rendering the patients euthyroid. Right ventricular dysfunction and pulmonary hypertension are not well-recognized complications of thyrotoxicosis. They are life-threatening conditions that can be reversed with early recognition and treatment of thyrotoxicosis. Signs and symptoms of right ventricular dysfunction should be sought in all patients with newly diagnosed thyrotoxicosis, and prompt restoration of euthyroidism is warranted in affected patients before the development of overt right heart failure.

    Learning points: Thyrotoxicosis is associated with right ventricular dysfunction and pulmonary hypertension apart from left ventricular dysfunction described in typical thyrotoxic cardiomyopathy.Symptoms and signs of right ventricular dysfunction and pulmonary hypertension should be sought in all patients with newly diagnosed thyrotoxicosis.Thyrotoxicosis should be considered in all cases of right ventricular dysfunction or pulmonary hypertension not readily explained by other causes.Prompt restoration of euthyroidism is warranted in patients with thyrotoxicosis complicated by right ventricular dysfunction with or without pulmonary hypertension to allow timely resolution of the abnormal cardiac parameters before development of overt right heart failure.

    Introduction: Tachycardia, or elevated heart rate is one of the important clinical parameters considered when diagnosing pulmonary embolism (PE) based on Wells' criteria. However, tachycardia is not highly specific and commonly presents in many other conditions.

    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.

    This report describes the complications of obstructive urolithiasis in the lower urinary tract causing urinary bladder rupture in a Jamnapari buck. A 3-year-old Jamnapari buck was presented with the complaint of stranguria, subsequent anuria and a progressively distended abdomen for the past three days. Upon physical examination, body temperature, pulse rate and respiration rate were increased. Uroliths could be felt within the urethra in the ventral abdomen region. A urolith was removed via amputationof the urethral process, but the patency of the urethra could not be established. Transabdominal ultrasound revealed anechoic areas around the bladder, and the bladder was relatively small for a urinary obstructed goat. The bladder wall was thickened and shadow of sludge was observed within the bladder. Abdominocentesis was done and fluid analysis revealed that it was a haemorrhagic effusion. Blood results revealed renal disease, liver disease, muscle injury and haemoconcentration. Retrograde cystourethrogram revealed no urolithswithinthe urethra but there was leakage of the contrast agent from the bladder into the peritoneal cavity. The final diagnosis was complete blockage of the lower urinary tract leading to bladder rupture. Exploratory laparotomy was done and emergency cystorraphy was planned. Due to the poor condition of the urinary bladder with presence of septic peritonitis, the goat was euthanised.

    Cardiovascular disease (CVD) is a growing burden across the world. In Asia and the Middle East, in particular, CVD is among the most prevalent and debilitating diseases. Dyslipidemia is an important factor in the development of atherosclerosis and associated cardiovascular events, and so effective management strategies are critical to reducing overall cardiovascular risk. Multiple dyslipidemia guidelines have been developed by international bodies such as the European Society of Cardiology/European Atherosclerosis Society and the American College of Cardiology/American Heart Association, which all have similarities in practice recommendations for the optimal management of dyslipidemia. However, they differ in certain aspects including pharmacological treatment, lifestyle modification and the target levels used for low-density lipoprotein cholesterol. The evidence behind these guidelines is generally based on data from Western populations, and their applicability to people in Asia and the Middle East is largely untested. As a result, practitioners within Asia and the Middle East continue to rely on international evidence despite population differences in lipid phenotypes and CVD risk factors. An expert panel was convened to review the international guidelines commonly used in Asia and the Middle East and determine their applicability to clinical practice in the region, with specific recommendations, or considerations, provided where current guideline recommendations differ from local practice. Herein, we describe the heterogeneous approaches and application of current guidelines used to manage dyslipidemia in Asia and the Middle East. We provide consensus management recommendations to cover different patient scenarios, including primary prevention, elderly, chronic kidney disease, type 2 diabetes, documented CVD, acute coronary syndromes and family history of ischemic heart disease. Moreover, we advocate for countries within the Asian and Middle East regions to continue to develop guidelines that are appropriate for the local population.

    Aim: This study aims to determine the perception of adult patients towards the importance of prevention of coronary artery diseases (CAD) in order to raise awareness on the risk of CAD.
    Method: 80 adults between 18-40 years old were enrolled in the out-patient department at a private hospital. The awareness and perception of the importance of preventing CAD were assessed using a questionnaire.
    Result: The level of perception on the importance of prevention of CAD was quite good. 75% of the subjects (n = 60) recorded good level of perception meaning they are aware of the importance of prevention of CAD. 22.5% of the subjects (n = 18) recorded a satisfactory level of perception while only 2.5% of the subjects (n = 2) recorded a poor level of perception towards the importance of prevention of CAD. Majority of the subjects had good perception on importance of a balanced diet, exercise and active lifestyle.
    Conclusion: In conclusion it can be said that although people are aware of the risk posed by CAD, recommendations such as proper health teachings and guide lines are still required to ensure that the community is able to understand the risk and take preventive measure in order to reduce the risk of obtaining the risk of heart disease.

    OBJECTIVE: To investigate the association of hypertension coexisting with diabetes mellitus with oxidative stress and inflammation in the kidneys of streptozotocin (STZ)-induced diabetic rats.

    MATERIALS AND METHODS: Male Wistar rats were used for the experiments. Blood glucose (BG), urea, blood pressure (BP), and heart rate (HR) were analyzed before and 48 h after STZ injection. Further, these parameters were monitored up to 3 months of diabetes induction. Subsequently, the inflammatory markers (C-reactive protein, tumor necrosis factor-alpha, and nitrate) and oxidative stress markers were estimated after 3 months of diabetes induction in the kidney homogenate. Histological analysis of renal tissue was also carried out.

    RESULTS: Linear elevation of BG, urea, mean arterial pressure (MAP), and HR was observed up to 3 months of diabetes induction. In the same manner, inflammatory and oxidative stress markers were also found to be significantly increased. Notably, the histological analysis revealed the signs of nephropathy such as increased mesangial cell number, thickness of basement membrane, and renal artery. Inflammatory and oxidative stress markers positively correlated with elevated BP and BG, but the correlation was better with BP rather than BG.

    CONCLUSION: Hypertension has a strong implication in the increased oxidative stress and inflammation of diabetic kidney at the very early stage of diabetes mellitus.

    Obstructive sleep apnea (OSA) is a growing health hazard in the United States and worldwide. OSA is now recognized as a disorder with systemic manifestations and its association with obesity and adverse cardiovascular consequences. There is increasing evidence that OSA may be associated with systemic hypertension and an increased incidence of stroke, heart failure, myocardial infarction, and arrhythmias. Less information is available about the association between OSA and pulmonary hypertension (PH). We therefore conduct this study to look at the prevalence of the pulmonary hypertension in obstructive sleep apnea patient and to identify risk factors leading to pulmonary hypertension among OSA patient. We studied and analyzed all OSA patient confirmed by polysomnograph in the year 2015. Twenty-five patients with OSA were included in this study with prevalence of pulmonary hypertension of 16%. Univariate analysis of various factors revealed a statistically significant association between having the lowest SpO2 of <70% and pulmonary hypertension (p = 0.016). There were no statistically significant associations between age, gender, smoking status, hypertension, body mass index (BMI), or apnea-hypopnea index (AHI) with occurrence of pulmonary hypertension. AHI is not a good predictor for pulmonary hypertension. The real value of using AHI to predict the health risk of OSA is doubtful. We recommend routine echocardiogram among OSA patient. The objective information in the echocardiogram provides evidence for counseling of patient with disease of OSA and hence hopefully can improve compliance of patient to treatment especially usage of CPAP.

    Acute myocardial infarction (AMI) and the heart failure (HF) that often follows are among the leading causes of death and disability worldwide. As such novel therapies are needed to reduce myocardial infarct (MI) size, and preserve left ventricular (LV) systolic function in order to reduce the propensity for HF following AMI. Mitochondria are dynamic organelles that can undergo morphological changes by two opposing processes, mitochondrial fusion and fission. Changes in mitochondrial morphology and turnover are a vital part of maintaining mitochondrial health, DNA stability, energy production, calcium homeostasis, cellular division, and differentiation, and disturbances in the balance of fusion and fission can predispose to mitochondrial dysfunction and cell death. Changes in mitochondrial morphology are governed by mitochondrial fusion proteins (Mfn1, Mfn2 and OPA1) and mitochondrial fission proteins (Drp1, hFis1, and Mff). Recent experimental data suggest that mitochondria undergo fission during acute ischemia/reperfusion injury (IRI), generating fragmented dysfunctional mitochondrial and predisposing to cell death. We and others have shown that genetic and pharmacological inhibition of the mitochondrial fission protein Drp1 can protect cardiomyocytes from acute IRI and reduce MI size. Novel components of the mitochondrial fission machinery, mitochondrial dynamics proteins of 49 kDa (MiD49) and mitochondrial dynamics proteins of 51 kDa (MiD51), have been recently described, which have been shown to mediating mitochondrial fission by targeting Drp1 to the mitochondrial surface. In this review article, we provide an overview of MiD49 and MiD51, and highlight their potential as novel therapeutic targets for treating cardiovascular diseases such as AMI, anthracycline cardiomyopathy, and pulmonary arterial hypertension.

    During induction of general anaesthesia, the act of laryngoscopy and tracheal intubation stimulates the sympathetic
    nervous system resulting in an increase in blood pressure and heart rate which may be harmful especially in elderly
    patients with pre-existing ischaemic heart disease. Several drugs have therefore been used to obtund this increase
    including esmolol, nicardipine, magnesium sulphate and lignocaine. This prospective, double blind randomised
    clinical trial compared the efficacy of magnesium sulphate and esmolol in attenuating haemodynamic responses to
    laryngoscopy and tracheal intubation. One hundred and twenty six ASA I-II patients scheduled for elective surgery

    Kinesiology-type tape (KTT) has become popular in sports for injury prevention, rehabilitation, and performance enhancement. Many cyclists use patella KTT; however, its benefits remain unclear, especially in uninjured elite cyclists. We used an integrated approach to investigate acute physiological, kinematic, and electromyographic responses to patella KTT in twelve national-level male cyclists. Cyclists completed four, 4-minute submaximal efforts on an ergometer at 100 and 200 W with and without patella KTT. Economy, energy cost, oxygen cost, heart rate, efficiency, 3D kinematics, and lower-body electromyography signals were collected over the last minute of each effort. Comfort levels and perceived change in knee stability and performance with KTT were recorded. The effects of KTT were either unclear, non-significant, or clearly trivial on all collected physiological and kinematic measures. KTT significantly, clearly, and meaningfully enhanced vastus medialis peak, mean, and integrated electromyographic signals, and vastus medialis-to-lateralis activation. Electromyographic measures from biceps femoris and biceps-to-rectus femoris activation ratio decreased in either a significant or clinically meaningful manner. Despite most cyclists perceiving KTT as comfortable, increasing stability, and improving performance, the intervention exerted no considerable effects on all physiological and kinematic measures. KTT did alter neuromuscular recruitment, which has potential implications for injury prevention.

    Cardiovascular diseases (CVDs) such as angina, hypertension, myocardial ischemia, and heart failure are the leading causes of morbidity and mortality worldwide. One of the major transcription factors widely associated with CVDs is nuclear factor-kappa B (NFκB). NFκB activation initiates the canonical and non-conical pathways that promotes activation of transcription factors leading to inflammation, such as leukocyte adhesion molecules, cytokines, and chemokines. Flavonoids are bioactive polyphenolic compounds found abundantly in various fruits, vegetables, beverages (tea, coffee), nuts, and cereal products with cardiovascular protective properties. Flavonoids can be classified into six subgroups based on their chemical structures: flavanones, flavones, flavonols, flavan-3-ols, isoflavones, and anthocyanidins. As NFκB inhibitors, these flavonoids may modulate the expression of pro-inflammatory genes leading to the attenuation of the inflammatory responses underlying various cardiovascular pathology. This review presents an update on the anti-inflammatory actions of flavonoids via inhibition of NFκB mechanism supporting the therapeutic potential of these natural compounds in various CVDs.

    BACKGROUND: Staphylococcus has replaced streptococcus as the most common cause of infective endocarditis (IE) in developed health care systems. The trend in developing countries is less clear.

    AIM: To examine the epidemiological trends of infective endocarditis in a developing nation.

    METHODS: Single-centre, retrospective study of patients admitted with IE to a tertiary hospital in Malaysia over a 12-year period.

    RESULTS: The analysis included 182 patients (n = 153 Duke's definite IE, n = 29 possible IE). The mean age was 51 years. Rheumatic heart disease was present in 42%, while 7.6% were immunocompromised. IE affected native valves in 171 (94%) cases. Health-care associated IE (HCAIE) was recorded in 68 (37.4%). IE admission rates increased from 25/100,000 admissions (2012) to 59/100,000 admissions (2017). At least one major complication on admission was detected in 59 (32.4%) patients. Left-sided IE was more common than right-sided IE [n = 159 (87.4%) vs. n = 18 (9.9%)]. Pathogens identified by blood culture were staphylococcus group [n = 58 (40.8%)], streptococcus group [n = 51 (35.9%)] and Enterococcus species [n = 13 (9.2%)]. staphylococcus infection was highest in the HCAIE group. In-hospital death occurred in 65 (35.7%) patients. In-hospital surgery was performed for 36 (19.8%) patients. At least one complication was documented in 163 (85.7%).

    CONCLUSION: Staphylococcus is the new etiologic champion, reflecting the transition of the healthcare system. Streptococcus is still an important culprit organism. The incidence rate of IE appears to be increasing. The rate of patients with underlying rheumatic heart disease is still high.

    Malaysia, like many aspiring developing countries, is undergoing a health transition that has seen the concomitant decrease in communicable diseases and increase in chronic diseases due to urbanization, modernization and ageing population. Health in the Malaysian society will thus increasingly focus on emerging problems that are both chronic and infectious in nature, such as, heart disease, diabetes, cancer, mental health, hepatitis and HIV/AIDS. Re-emerging diseases previously well-controlled, such as, tuberculosis for instance is another addition to these immediate health issues facing Malaysian society today. Despite the tremendous health gains and above average health status that Malaysians now enjoy, we are compelled to take stock of these urgent issues as well as to anticipate and handle serious challenges to our health in the 21st century. In this paper, we review the changing trends and discuss related challenges in disease pattern, environmental health, demographic impacts on health, migration influxes and health, effects of globalization on health, mental health and wellness as well as fundamental access and equality in health care. Being proactive, resilient and innovative, Malaysian society would forge ahead towards our Vision for Health in this new era.
