    Aflatoxins (AFs) are secondary metabolites toxic to humans as well as animals. The environmental conditions, conventional agricultural practices, and illiteracy are the main factors which favor the production of AFs in food and feed. In the current study 744 samples of vegetable seeds and oils (soybean, sunflower, canola, olive, corn, and mustard) were collected and tested for the presence of aflatoxin B1 (AFB1) and total AFs. Liquid-liquid extraction was employed for the extraction of AFs from seeds and oil samples. Reverse phase high performance liquid chromatography equipped with fluorescence detection was used for the analysis. The results have shown that 92 (56.7%) samples of imported and 108 (57.0%) samples of local edible seeds were observed to be contaminated with AFs. All samples of edible seeds have AFB1 levels greater than the proposed limit set by the European Union (EU, 2 µg/kg) and 12 (7.40%) samples of imported seeds and 14 (7.40%) samples of local seeds were found in the range ≥ 50 µg/kg. About 78 (43.3%) samples of imported edible oil and 103 (48.3%) sample of local edible oil were observed to be positive for AFs. Furthermore, 16 (8.88%) and six (3.33%) samples of imported vegetable oil have levels of total AFs in a range (21-50 µg/kg) and greater than 50 µg/kg, respectively. The findings indicate significant differences in AFs levels between imported and local vegetable oil samples (t = 22.27 and p = 0.009) at α = 0.05 and a significant difference in AFs levels were found between vegetable seeds and oil samples (t = -17.75, p = 0.009) at α = 0.05. The highest dietary intake was found for a local sunflower oil sample (0.90 µg/kg/day) in female individuals (16-22 age group). The results have shown considerably high levels of AFB1 and total AFs in seeds and oil samples and emphasise the need to monitor carefully the levels of these toxic substances in food and feed on regular basis.

    Introduction: There are numerous studies on the therapeutic properties of Artocarpus heterophyllus. However, stud- ies on the aqueous extraction of A. heterophyllus leaves are limited. This present study was conducted to optimize the extraction conditions of A. heterophyllus leaves to yield the highest phenolic, flavonoids and antioxidant contents. Methods: Response surface methodology (RSM) was employed to obtain a higher phenolic extraction parameter(s) of A. heterophyllus leaves using Central Composite Design (CCD). The antioxidant activity was then determined via ABTS (2,29-azinobis (3 ethylbenzothiazoline-6-sulfonic acid)) and DPPH (2,2-Diphenyl-1-picrylhydrazyl) assay and analysis of the individual phenolics was performed by high performance liquid chromatography (HPLC). Results: The optimum extraction conditions with higher phenolics content and antioxidant activity was achieved at 81°C, 100 min and 40 mL/g sample with a good desirability value of 0.87. Under these optimized parameters, total phenolics and flavonoids were 174.48 ± 4.05 mg GAE/g sample and 21.44 ± 0.05 mg RE/g sample, respectively. Meanwhile, antioxidant activity via ABTS and DPPH assays were 90.88% ± 0.09 and 87.22% ± 0.62, respectively. Finally, under optimal extraction conditions revealed 4 compounds identified as chlorogenic acid, quercetin, rutin and kaempferol. Conclusion: The optimisation are promising to improve phenolic yield and antioxidant activity in A. heterophyllus leaves. It also proved that A. heterophyllus leaves can be used as an alternative natural antioxidant especially in medicinal applications since all identified compound possess significant biological activities for human health.

    Lupinus albus or white lupine has recently received increase attention for its medicinal values. Several studies have described the hypoglycemic effect of the white lupine, which is known as a food plant with potential value for treatment of diabetes. This study provides useful information for the identification and quantification of compounds in L. albus fractions by proton nuclear magnetic resonance (1H NMR) spectroscopy. In total, 35 metabolites were identified from L. albus fractions.Principal component analysis (PCA) was used as a multivariate projection method for visualizing the different composition of four different fractions. The bioactivities of fractions with different polarity obtained from the extract of L. albus seeds are reported. Among the fractions studied, the chloroform fraction (CF) exhibits a high free radical scavenging (DPPH) and α-glucosidase inhibitory activities with IC50 values of 24.08 and 20.08 μg/mL, respectively. A partial least-squares analyses (PLS) model had been successfully performed to correlate the potential active metabolites with the corresponding biological activities. Metabolites containing proline, caprate, asparagine, lupinoisolone C, hydroxyiso lupalbigenin and some unknown compounds show high correlation with the bioactivities studied. Moreover, the structural identification in the active fraction was supported by ultrahigh-performance-liquid chromatography-electrospray ionization tandem mass spectrometry (UHPLC-ESI-MS/MS) analysis. A total of 21 metabolites were tentatively identified from MS/MS data by comparison with previously reported data. Most of these compounds are isoflavonoids without known biological activity. This information may be useful for developing functional food from L. albus with potential application in the management of diabetes.

    Stability indicating assay describes a technique which is used to analyse the stability of drug substance or active pharmaceutical ingredient (API) in bulk drug and pharmaceutical products. Stability indicating assay must be properly validated as per ICH guidelines. The important components in a stability indicating assay include sensitivity, specificity, accuracy, reliability, reproducibility and robustness. A validated assay is able to measure the concentration changes of drug substance/API with time and make reliable estimation of the quantity of the degradation impurities. The drug substance is separated and resolved from the impurities. Pros and cons of HPLC, GC, HPTLC, CE and SFC were discussed and reviewed. Stability indicating assay may consist of the combination of chromatographic separation and spectroscopic detection techniques. Hyphenated system could demonstrate parallel quantitative and qualitative analysis of drug substances and impurities. Examples are HPLC-DAD, HPLC-FL, GC-MS, LC-MS and LC-NMR. The analytes in the samples are separated in the chromatography while the impurities are chemically characterised by the spectroscopy in the system. In this review, various chromatographic methods which had been employed as stability indicating assays for drug substance and pharmaceutical formulation were systematically reviewed, and the application of hyphenated techniques in impurities characterisation and identification were also discussed with supporting literatures.

    Introduction: Pesticides may influence the physicochemical properties of soil and the water quality parameters, which is vital in maintaining soil fertility and producing high quality crops. Objective: This study aims to determine the relationship between the concentration of pesticides, the physicochemical properties of the paddy soil samples and the water quality parameters of paddy water samples. Methods: A total of 72 soil and 72 water samples were collected in Tanjung Karang, Malaysia. The paddy soil and water were extracted using Quick, Easy, Cheap, Efficient, Rugged and Safe (QuEChERS) and solid phase extraction (SPE) techniques respectively. The concentrations of pesti- cides were analysed in ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). The relationship of the concentration of target pesticides and the paddy soil and water physicochemical properties were studied using Spearman correlation. Results: In paddy soil, the concentration of propiconazole shows moderate positive correlation with manganese (Mn) (r = 0.587) (p 0.01). Meanwhile buprofezin-total organic carbon (TOC) (r = -0.55) (p 0.01), imidacloprid-cation exchange capacity (CEC) (r = -0.519) (p 0.01), pymetrozine-sodium (Na) (r = -0.588) (p 0.01), and trifloxystrobin-calcium (Ca) (r = 0.566) (p 0.01) showed moderate negative correlation. Whereas in water, trifloxystrobin showed significant positive correlation with turbidity (r = 0.718) (p 0.01) and te- buconazole showed negative correlation to dissolved oxygen (DO) (r = 0.634) (p 0.01). Conclusion: The presence of pesticides in paddy field may influence the soil and water quality, thus regular monitoring of pesticides usage and nutrient management in soil is deemed important.

    BACKGROUND: Subliminal transscleral cyclophotocoagulation (SL-TSCPC) is a new alternative therapy to reduce intraocular pressure (IOP) safely and effectively. However, there are few studies regarding SL-TSCPC by Supra 810 laser machine and limited data regarding its effectiveness in moderate severity glaucoma that still has good preservation of vision. This study was conducted to evaluate the outcome of SL-TSPCPC in various types of glaucoma including patients with good vision.

    METHODS: A retrospective, non-comparative, analytical case series of all patients who received SL-TSCPC treatment from October 2018 to April 2019 at Hospital Tengku Ampuan Afzan, Pahang, Malaysia. Data was collected during the second week, sixth week, third month and sixth month follow-up. The primary outcome measure gave success rate at six months post-treatment. Secondary measures were changes in visual acuity, mean IOP reduction, mean number of IOP lowering medications reduced and ocular side effects noted during follow-up.

    RESULTS: The success rate was 43.8% (seven eyes out of sixteen eyes) at six months post-treatment. The mean IOP reduced from 43.0mmHg±14.8mmHg pre-treatment to 24.7mmHg±12.0mmHg at two weeks post treatment with 42.6% reduction. Subsequently, mean IOP at sixth week, third month and sixth month were 33.8mmHg±16.9mmHg, 35.2mmHg±14.9mmHg, and 29.0mmHg±16.2mmHg respectively. Vision maintained in 13 patients, two patients had improvement in vision however, five patients had deterioration in vision. No serious ocular side effects were noted.

    CONCLUSION: Subliminal TSCPC is a safe and alternative method of lowering IOP in moderate to advanced glaucoma over 6 months duration of follow-up. As it has good safety profile and repeatability, it is a good treatment option for patients with uncontrolled glaucoma.

    Hypertension is a worldwide problem and a major global health burden with high salt intake as one of the factors often related to it. Public exposure to a high salt diet has contributed to the increase in prevalence of hypertension among the Malaysian population. Improving the knowledge, attitudes and practices (KAP) related to salt intake is a key component of effective blood pressure control. Therefore, this study was aimed to determine the association of KAP of healthy salt intake toward blood pressure among the elderly residing in a semi urban area of Klang Valley Malaysia. A cross-sectional study using convenience sampling was conducted among Malay elderly, aged 60-81 years old residing in Bandar Baru Bangi. Subjects were required to answer the questionnaire via face to face interview regarding KAP of Salt Intake, together with sociodemographic and health profiles. Anthropometry parameters and blood pressure were measured. A total of 94 elderly [57.5% women with mean Body Mass Index (BMI) of 26. 46 ± 4.16, 42.5% men with mean BMI of 27.31 ± 5.19] have participated in the study. Results indicated that the overall KAP score was average (57.4%). However, majority showed a positive attitude toward reducing the salt intake. BMI was found to have significant correlation with blood pressure (r = 0.278, p < 0.05). Higher education level was significantly (p < 0.05) associated with good knowledge scores while younger subjects have a positive attitude toward healthy intake of salt (p < 0.05). Subjects with higher knowledge scores were also observed to have the more controlled blood pressure compared to those who scored less. Attitude and practices score showed no significance difference (p > 0.05) with blood pressure. Younger age, higher level of education and living partner or elderly was significantly (p < 0.05) associated with lower systolic and diastolic blood pressure. Overall, this study showed that knowledge toward healthy salt intake, BMI, education level, and living with others were significantly associated with the blood pressure among the elderly. Further education and intervention is required to improve knowledge on healthy salt intake among elderly as part of the prevention from hypertension.

    Hypertensive emergency in the paediatric population is not uncommon. However, due to its numerous etiologies, care should be taken in determining the approach of management. We report a case of a child who presented with double vision, giddiness and elevated blood pressure. Blood investigations were normal. Renal ultrasound and magnetic resonance imaging of the abdomen were performed which both showed findings suspicious of a large heterogeneous mass at the lower pole of the left kidney with dysplastic right kidney. A final diagnosis of bilateral vesicoureteric reflux with left compensatory hypertrophy was made based upon micturating cystourethrography findings and was later confirmed by 99mTc-dimercaptosuccinic acid (DMSA) study. The objective of this case is to share the importance of the appropriate choice of radiological examinations, not only in achieving an accurate diagnosis but to ensure that unnecessary investigations are avoided.

    Strobilanthes crispus and Clinacanthus nutans are popular herbal plants in the Southeast
    Asian region. The present work was aimed at determining the antioxidant activities and the
    associated components in the leaf extracts of both species using polar and non-polar solvents
    namely water, methanol, ethyl acetate, and hexane. The total phenolic content (TPC) and total
    flavonoid content (TFC) were higher in the leaf extracts of S. crispus as compared to C.
    nutans. Among the solvents, methanol was the best solvent in extracting the antioxidant
    components for S. crispus (TPC: 159.85 ± 0.89 mg GAE/g extract and TFC: 955.47 ± 2.66 mg
    RE/g extract). However, for C. nutans, its methanolic extract yielded the highest TPC (36.39
    ± 0.17 mg GAE/g extract), whereas ethyl acetate yielded the highest TFC (229.61 ± 7.81 mg
    RE/g extract). The high levels of both TPC and TFC contributed to the antioxidant activities
    of S. crispus extract as reflected in the methanolic extract attaining the highest level of
    antioxidant activities, measured by ferric reducing antioxidant power (FRAP) (6.84 ± 1.12
    mmol Fe2+/g extract), DPPH radical scavenging (IC50: 203.60 ± 7.28 μg/mL), and Trolox
    equivalent antioxidant capacity (TEAC) (1.01 ± 0.01 mmol TE/g extract) assays. This
    contrasted with C. nutans which showed lower antioxidant activities owing to its lower TPC
    and TFC. Correlation analysis revealed significant correlations (p < 0.05, r = 0.915 - 0.985)
    between both TPC and TFC in S. crispus and antioxidant activities. However, only TPC of C.
    nutans showed a significant correlation with FRAP values (r = 0.934). Further tentative
    identification of the constituents in the extracts using HPLC-ESI-QToF-MS/MS revealed the
    existence of 20 polyphenolic compounds in both S. crispus and C. nutans, which were likely
    responsible for their antioxidant activities. In addition, 15 polyphenolic compounds classified
    as chalcones, isoflavanoids, flavones, and flavonols have not been previously reported in both
    species. The methanolic extracts of both species yielded a higher content of antioxidants, with
    S. crispus offering a richer source of dietary antioxidants as compared to C. nutans. However,
    further study is needed to identify their bioactivities in relation to their bioactive components.

    Introduction: Short-term fasting may influence intraocular pressure (IOP) due to alteration of fluid (total body water;
    TBW, and water intake) and fat (total body fat; TBF). This study aimed: i) to compare IOP values within and between,
    fasting and non-fasting periods; and ii) to assess the association between IOP and, TBW and TBF. Methods: Thirty
    healthy participants aged 21.8±1.1 years were assessed on two different periods (fasting vs. non-fasting). During each
    period, the IOP, TBW and TBF values were assessed for four times (morning, afternoon, evening, late-evening). The
    IOP was measured using AccuPen® tonopen, while TBW and TBF were assessed by using a Tanita body composition
    analyser. Results: During fasting, the IOP value in the afternoon (14.53±2.33 mmHg) was significantly higher than in
    the evening (12.43±2.73 mmHg, p=0.009) and late-evening (12.60±2.44 mmHg, p=0.003). No significant difference
    in IOP was observed during non-fasting period. The mean of IOP in the evening was significantly lower during fasting
    compared to non-fasting (12.43±2.73 mmHg vs 13.75±2.53 mmHg, p=0.044). The IOP and TBW were negatively
    correlated (r=-0.268; p=0.011) during non-fasting and showed no association during fasting period. There was no
    significant correlation between IOP and TBF during both fasting and non-fasting periods. Conclusion: IOP reduction
    during short-term fasting, together with the no association with TBF and TBW suggested that IOP is an independent
    factor that reduces during fasting in healthy population.

    The continuous presence of elevated blood pressure (BP) when young is a strong predictor of future cardiovascular risk. This study aimed to elucidate the prevalence, awareness, treatment and control of young-onset hypertension (YOH) in Malaysia during the period 2006-2015. Data on respondents aged 18-39 diagnosed with YOH according to the 7th Joint National Committee Report (USA) were extracted from three National Health and Morbidity Surveys (2006, 2011, and 2015). The prevalence of YOH remained stable: 17.7%, 95% CI [17.0, 18.3] in 2006, 17.0%, 95% CI [16.0, 17.9] in 2011 and 18.4%, 95% CI [17.4, 19.4] in 2015. Awareness, treatment and control rates were suboptimal; 15% were aware of their diagnosis, of which less than 50% were on treatment and less than 40% who were on treatment had their BP controlled. Trend analysis revealed a significant increase in YOH prevalence among urban dwellers; those with no formal and tertiary education and middle-income earners. YOH awareness and treatment rates were lower among respondents <30 years; however, when treated, this group achieved overall better control rates. Females had higher awareness and treatment rates, but lower control. Treatment rates remained stable for all ethnicities with the exception of Chinese, which decreased. This study narrows the knowledge gap on YOH epidemiology in Malaysia by providing crucial information on the pervasiveness of hypertension among young adults. Results can be used to develop non-communicable disease policies and health promotion strategies specially targeted at young adults who are in the prime of life.

    The optimum combination of Baccaurea angulata fruit juice (X1: 15 - 85 ratio) and Trigona sp. honey (TH) (X2: 15 - 85 ratio) in developing a high antioxidant soft jelly was investigated based
    on the antioxidant capacity (Y1), phenolic (Y2), and flavonoid (Y3) content. Response surface
    methodology (RSM), via central composite design (CCD), was used to produce optimal combination effects of the two independent variables (B. angulata fruit juice and TH) for highest
    recovery of antioxidant capacity (AC), total phenolic content (TPC), and total flavonoid content
    (TFC). The polynomial models generated were satisfactory. The lack-of-fit test were higher
    than p > 0.05 for all three analyses, signifying the suitability of the models in accurately predicting the variations. Predicted values of the analysis agreed with those of the experimental values.
    An optimum combination of B. angulata fruit juice and TH was developed (ratio 40:40). The
    sample also exhibited significant FRAP and DPPH radical scavenging activities. Several
    polyphenols were identified for the samples through UHPLC-MS/MS. In conclusion, B. angulata and Trigona sp. honey have high potentials to be used in fortifying the soft jelly samples,
    making them prospective food supplements due to their nutritional and health benefits.

    Introduction: Ocimum basilicum (OB), a herb known for its antihypertensive,
    anticholinesterase and antioxidant properties was investigated for possible intraocular
    pressure (IOP) lowering effects in rabbits with ocular hypertension (OHT). Methods: The
    IOP lowering effect of a single drop of OB extract (OBE) was evaluated in oculonormotensive
    rabbits using three concentrations (0.25, 0.5 and 1% w/v). The concentration showing
    maximum IOP reduction was further evaluated in rabbits with water-loading and steroidinduced OHT. Results: IOP lowering effect of OBE 0.5% in oculonormotensive rabbit eyes
    was significantly greater compared to OBE 0.25% (p0.05) to
    OBE 1%. Therefore, 0.5% concentration was selected for further evaluation. Pretreatment
    with OBE (0.5%) caused significantly lower increase in IOP after water loading amounting to
    23.39% above baseline as compared to 54.00% in control eye, 15 minutes post water
    loading. At 60 minutes, post water loading, mean IOP rise was 95.12% and 63.58% in
    control and test eyes, respectively. Significant difference between the mean IOP of two eyes
    persisted during the 2nd hr. In rabbits with steroid induced OHT, OBE 0.5% produced a
    mean IOP reduction of 24.73% at the end of first hr and the mean peak IOP reduction of
    31.63% was observed at the end of 2 hr. A significant difference between the IOP of test and
    control eyes persisted from 1 to 6 hr. Conclusions: Ocimum basilicum seed extract showed
    significant IOP lowering effect in rabbits with water loading and steroid induced OHT,
    however, its utility as an effective antiglaucoma medication needs further investigations.

    Primary aldosteronism (PA) causes a persistently elevated blood pressure (BP) due to
    excessive release of the hormone aldosterone from the adrenal glands. Classically, it is called
    Conn’s syndrome and is described as the triad of hypertension and hypokalemia with the
    presence of unilateral adrenal adenoma. It can be cured with surgical resection of the
    aldosterone-secreting adenoma leading to resolution of hypertension, hypokalemia and
    increased cardiovascular risk associated with hyperaldosteronism. We present a case of a man
    with previous ischemic heart disease (IHD) who presented with resistant hypertension.
    Investigations for secondary causes of hypertension revealed an elevated aldosterone level
    and saline suppression test confirmed the diagnosis of PA. Radiological examination revealed
    a left adrenal adenoma and a normal right adrenal gland. However, adrenal venous sampling
    showed lateralization of aldosterone secretion towards the right. He subsequently underwent
    a laparoscopic right adrenalectomy which improved his BP control promptly. This case
    highlights the importance of recognizing the need to investigate for secondary causes of
    hypertension. It also underscores the importance of dynamic tests, which may not be easily
    accessible to most clinicians but should pursue, to allow a definitive diagnosis and effective
    treatment.

    Anagallis arvensis L. commonly known as 'Scarlet Pimpernel' has been used in folklore as natural remedy for treating common ailments. The present research is aimed to explore the phytochemical composition and enzyme inhibition potential of methanol and dichloromethane (DCM) extracts of A. arvensis aerial and root parts. The phytochemical composition was established via HPLC-PDA polyphenolic quantification and UHPLC-MS analysis, while the inhibition potential against amylase and tyrosinase enzymes were assessed using standard in vitro protocols. The HPLC-PDA polyphenolic quantification revealed the presence of important compounds including catechin, gallic acid, chlorogenic acid, and ferulic acid, whereas 34 different secondary metabolites were tentatively identified by UHPLC-MS of both the DCM extracts. All the extracts showed moderate tyrosinase and a weak amylase inhibition activity. The aerial-DCM extract showed comparatively higher tyrosinase and amylase enzyme inhibition potential, which may be due to the presence of secondary metabolites as tentatively identified by its UHPLC-MS profiling.

    This study aimed to examine the relationship of adherence with blood pressure (BP) control and its associated factors in hypertensive patients. This cross-sectional nationwide BP screening study was conducted in Malaysia from May to October 2018. Participants with self-declared hypertension completed the Hill-Bone Compliance to High Blood Pressure Therapy Scale (Hill-Bone CHBPTS) which assesses three important domains of patient behavior to hypertension management namely medication taking, appointment keeping and reduced salt intake. Lower scores indicate better compliance while higher scores indicate otherwise. Participant's body mass index and seated BP were measured based on standard measurement protocol. Determinants of adherence to treatment were analyzed using multiple linear regression. Out of 5167 screened subjects, 1705 were known hypertensives. Of these, 927 (54.4%) answered the Hill-Bone CHBPTS and were entered into analysis. The mean age was 59.0 ± 13.2 years, 55.6% were female and 42.2% were Malays. The mean Hill-Bone CHBPTS score was 20.4 ± 4.4 (range 14-47), and 52.1% had good adherence. The mean systolic BP and diastolic BP were 136.4 ± 17.9 and 80.6 ± 11.6 mmHg, respectively. BP was controlled in 58.3% of those with good adherence compared to 50.2% in those with poor adherence (p = .014). Based on multiple linear regression analysis, female gender (β = -0.72, 95% confidence interval [CI] -1.30, -0.15, p = .014), older age (β = -0.05, 95% CI -0.07, -0.03, p

    OBJECTIVE: To identify the prevalence of hypertension and its relationship with dietary sodium intake among the Malay population in Selangor, Malaysia.

    Methods: Respondents were recruited from the year 2013 to 2015 from households in Klang Valley (urban area) and several settlements of the Federal Land Development Authority (FELDA) in Selangor (rural area). Data were collected using two questionnaires, a sociodemographic questionnaire and a food frequency questionnaire.

    RESULTS: A total of 3,453 adults participated in this study. The mean age of the respondents was 50.9 (±10.23) years. The prevalence of hypertension was 23.3%. Mean dietary sodium consumption was 3.6 (±6.63) grams/day, 1.6 grams higher than the current WHO recommendation. The prevalence of hypertension was higher among males aged 60 years and older; among rural population with low education level; among housewives and those with high dietary sodium intake. After adjusting for age, gender and marital status in a multiple logistic regression analysis, rural location (OR = 5.81) and high sodium intake (OR = 2.33) have been shown to affect the incidence of hypertension.

    CONCLUSIONS: A substantial proportion of Malay population in Selangor was hypertensive with a higher sodium intake than the WHO recommendation. Hypertension was associated with rural location and high sodium intake. Sustainable and cost-effective population-based health promotion and prevention interventions using a multi-sectoral approach are needed to ensure sufficient community sodium intake.

    BACKGROUND: The main risks for glaucoma are increased intraocular pressure (IOP) and decreased ocular perfusion pressure (OPP). This review aims to examine the potential impact of lower limb isometric resistance exercise on intraocular pressure and ocular perfusion pressure.

    METHOD: A meta-analysis was conducted to determine the potential impact of isometric exercise on IOP and OPP. The literature on the relationship between isometric resistance exercise and IOP was systematically searched according to the "Cochrane Handbook" in the databases of Pubmed, Web of Science, EBSCO, and Scopus through December 31, 2020. The search terms used were "exercise," "train," "isometric," "intraocular pressure," and "ocular perfusion pressure," and the mean differences of the data were analyzed using the Stata 16.0 software, with a 95% confidence interval.

    RESULTS: A total of 13 studies, which included 268 adult participants consisting of 162 men and 106 women, were selected. All the exercise programs that were included were isometric resistance exercises of the lower limbs with intervention times of 1min, 2min, or 6min. The increase in IOP after intervention was as follows: I2=87.1%, P=0.001 using random-effects model combined statistics, SMD=1.03 (0.48, 1.59), and the increase in OPP was as follows: I2=94.5%, P=0.001 using random-effects model combined statistics, SMD=2.94 (1.65, 4.22), with both results showing high heterogeneity.

    CONCLUSION: As isometric exercise may cause an increase in IOP and OPP, therefore, people with glaucoma and related high risk should perform isometric exercise with caution.

    A 2-year-old girl who was under genetic follow up for developmental delay and dysmorphism was accidentally found to have bilateral optic disc swelling during screening examination. She showed response to optokinetic drum examination and the anterior segment examination was unremarkable. Optic disc swellings were seen in both eyes. Lumbar puncture shows high opening pressure of 50 cm H2O with unremarkable CSF analysis. MRI of brain was done and showed features in keeping with mild cerebral atrophy, with no evidence of hydrocephalus or space oc- cupying lesion. She was diagnosed with idiopathic intracranial hypertension and oral acetazolamide 125mg bd was commenced. However, papilloedema persist despite medical therapy. Ventriculoperitonel shunt was inserted to re- duce the csf pressure. This case report highlights the importance of considering idiopathic intracranial hypertension as a cause of optic disc swelling in pre-pubertal children because delay in diagnosis and treatment may permanently affect visual function especially in children.

    Polycyclic aromatic hydrocarbons (PAHs) are hazardous and persistent organic pollutants that usually exist at low concentrations in the environment. In this study, dispersive liquid-liquid microextraction (DLLME) technique coupled with high performance liquid chromatography-fluorescence detection (HPLC-FD) was optimized for the analysis of selected PAHs, namely phenanthrene (PHE), fluoranthene (FLA) and benzo[a]pyrene (BaP) in apple juice. Under the optimal extraction conditions (the mixture of 200 µL of acetone and 50 µL of 1-octanol was applied to extract the selected PAHs for 1 min), the DLLME-HPLC-FD showed excellent linearity over the concentration range of 5 to 200 µg/L for both PHE and FLA, and 0.01 to 5 µg/L for BaP with correlation coefficients, r ≥ 0.9956. The method offered ultra-trace detection of selected PAHs in the range of 0.002 to 0.5 µg/L, and negligible matrix effects in determining selected PAHs with relative recovery average within the range of 92.6 to 109.6% in apple juice. The advantages of applying this method for the extraction of PAHs include rapidity, simple operation, as well as small consumption of organic extraction solvent, which is beneficial for routine analysis.
