    Diagnosing acute appendicitis in children can be difficult due to atypical presenting symptoms. While there are reported cases of acute appendicitis or appendiceal masses causing unilateral hydronephrosis, bilateral hydronephrosis as a complication of appendiceal mass is very rare. We report a case of a child who presented with cardinal symptomatology associated with the urogenital tract. Ultrasound (US) investigation showed a pelvic mass causing bilateral hydronephrosis. An initial diagnosis of a pelvic teratoma was made based on the US and computed tomography (CT) scan findings. The final diagnosis of an appendiceal mass causing bilateral hydronephrosis was established intraoperatively.

    The drug-trafficking business has risen tremendously because of the current increased demand for illegal narcotics. The smugglers conceal the drugs in their bodies (body packers) in order to bypass the tight security at international borders. A suspected body packer will normally be sent to the hospital for imaging investigations to confirm the presence of drugs in the body. Radiologists, therefore, need to be familiar with and able to identify drug packets within the human body because they shoulder the legal responsibilities. This pictorial essay describes the characteristic imaging features of drug packets within the gastrointestinal tract.

    The high-dimensional search space involved in markerless full-body articulated human motion tracking from multiple-views video sequences has led to a number of solutions based on metaheuristics, the most recent form of which is Particle Swarm Optimization (PSO). However, the classical PSO suffers from premature convergence and it is trapped easily into local optima, significantly affecting the tracking accuracy. To overcome these drawbacks, we have developed a method for the problem based on Hierarchical Multi-Swarm Cooperative Particle Swarm Optimization (H-MCPSO). The tracking problem is formulated as a non-linear 34-dimensional function optimization problem where the fitness function quantifies the difference between the observed image and a projection of the model configuration. Both the silhouette and edge likelihoods are used in the fitness function. Experiments using Brown and HumanEva-II dataset demonstrated that H-MCPSO performance is better than two leading alternative approaches-Annealed Particle Filter (APF) and Hierarchical Particle Swarm Optimization (HPSO). Further, the proposed tracking method is capable of automatic initialization and self-recovery from temporary tracking failures. Comprehensive experimental results are presented to support the claims.

    Reactive arthritis can be an elusive diagnosis especially in the elderly. A 77-year-old lady, presented with recent history of hip pain. She had been treated for urinary tract infection caused by Chlamydia sp. and had associated weight loss. She was also investigated for possible tuberculosis and occult malignancy. CT scan abdomen/pelvis and MRI revealed peri-articular muscle inflammation. Biopsy of her hip joint failed to find the causative factor. Whole body 18F-FDG PET/CT scan revealed increased FDG uptake at bilateral hip and shoulder joints. She recovered after an intensive course of antibiotics. Thus, she was diagnosed with reactive arthritis. Reactive arthritis is usually a diagnosis of exclusion made by a high index of suspicion and positive serology test. Molecular imaging can be an alternative investigation for joint pains in the elderly, which enables excellent anatomical and functional information to exclude more sinister conditions such as malignancy.

    Current re-emergence of Nipah virus (NiV) in India caused 11 deaths so far and many patients were kept in quarantine. A thorough study of previous outbreaks occurred in Malaysia, Bangladesh and India represents cases with high rate of fatality due to acute encephalitis. Our work involves genome analysis of NiV for prediction of miRNAs and their targeted genes in human in order to understand encephalitis origin. Ab-intio program-VMir was used for initial screening of genome, obtained nine pre-miRNAs was analyzed by ViralMir to check for any pseudo pre-miRNAs. Eighteen functional mature miRNAs were extracted from pre-miRNAs by using Mature-Bayes tool, which targets 669 genes in human genome as retrieved by miRDB. Gene ontology terms by PANTHER provide important pathways in which target genes were involved like Axon guidance, T cell activation, and nicotinic acetylcholine receptor signaling. Significant outcome was obtained after NCBI Gene and OMIM database mining and literature search for predicted target genes. TLR3, TJP1, NOTCH2, FHL1, and GRIA3 target genes obtained showed their involvement in host defense, blood brain barrier, neurogenesis, mental retardation and encephalitis. To conclude, we predicted significant genes in human that can be inhibited by miRNAs of NiV and results in etiology of encephalitis.

    BACKGROUND: Female sexual dysfunction (FSD) includes female orgasmic disorder, female sexual interest or arousal disorder, and genito-pelvic pain or penetration disorder. FSD affects 40% of women worldwide, but it is understudied and likely undertreated. Natural products are frequently used by women to treat FSD, but scientific evidence of their efficacy is lacking.

    OBJECTIVE: This systematic review and meta-analysis focused on the study of the efficacy of natural products on FSD.

    STUDY DESIGN: Systematic review and meta-analysis of existing studies on natural products in the treatment of FSD.

    METHODS: The literature search included MEDLINE, EMBASE, PsycINFO, and the Cochrane Central Register of Controlled Trial databases for studies published from January 2000 to February 2020. The quality and the level of evidence of the studies were assessed. The association between natural products and FSD was summarized using standardized mean differences (SMD) with a 95% confidence interval (CI).

    RESULTS: A total of 536 studies were identified, with 20 of them meeting the criteria. According to this meta-analysis, Tribulus terrestris showed a significant positive effect in improving overall female sexual function (SMD = 1.12, 95% CI = 0.46 - 1.79, p = 0.001) and individual sexual arousal (SMD = 1.03, 95% CI = 0.22 - 1.84, p = 0.013), sexual desire (SMD = 1.08, 95% CI = 0.52 - 1.63, p ≤ 0.001) and sexual orgasm (SMD = 0.51, 95% CI = 0.02 - 1.00, p = 0.040) domains compared to placebo. Panax ginseng was found to be effective in treating sexual arousal (SMD = 0.54, 95% CI = 0.11 - 0.97, p = 0.014) and sexual desire (SMD = 0.59, 95% CI = 0.27 - 0.90, p < 0.001) compared to placebo. Meanwhile, other natural products reviewed in this study, such as Trifolium pretense, did not differ significantly from placebo in terms of improving FSD.

    CONCLUSION: Preliminary evidence suggests that Tribulus terrestris and Panax ginseng may be effective as alternative treatments for FSD in a clinical setting.

    48,XXYY syndrome is a rare condition. The presentations of impulsive and aggressive behavior have been reported in several case reports among patients with 48,XXYY syndrome. The management of the psychological impact and neuropsychiatric sequela of this condition is a significant issue faced by families, carers, and healthcare professionals. We report a patient, 21-year-old Malay male, with underlying 48,XXYY syndrome with attention deficit hyperactivity disorder (ADHD) and intellectual disability, diagnosed later in adulthood with a bipolar mood disorder and benefited after being started on lithium. We describe the key clinical features and diagnostic workouts that allowed the arrival of the correct psychiatric diagnosis. Challenges in psychopharmacotherapy, including the risks of metabolic syndrome and deep vein thrombosis associated with 48,XXYY syndrome, are also considered. We suggest that for patients with 48,XXYY syndrome, routine psychological screening for mood symptoms such as mania and depression should be done by healthcare professionals with early involvement of psychiatrist in the multidisciplinary team due to the challenges in the management of these patients.

    The current education system significantly emphasizes tests and evaluations as crucial factors in determining a student's future career path. It has been shown that nursing students have moderate to high levels of Test Anxiety (TA), which results in decreased academic performance, low self-esteem, and an inability to complete the program and pursue a career in nursing successfully. This study aimed to determine nursing students' level of TA and its relationship with demographic characteristics. Four hundred twenty-one nursing students at seven private universities and colleges in Selangor participated in this cross-sectional study. The level of TA was measured using the TA Inventory (TAI). A total of 62.5% of the respondents had mild TA, 25.4% had moderate TA and 2.1% had severe TA. There were significant relationships between TA level and household income (χ2 = 6.70, p = 0.035) and ethnic groups (F (3,417) = 5.20, p = 0.002) where Chinese and Indians are protective from TA compared to the Malays and other ethnic groups and high anxiety was significant in the Ringgit Malaysia (RM 3000) and below group. The study's findings indicate that a significant percentage of nursing students involved in the research had mild to moderate levels of test anxiety (TA) and there is a significant association between TA and demographic characteristics. The results indicate the importance of early identification of TA and the need for interventions to overcome TA to ensure they are emotionally, physically, and academically successful.

    Background: Anxiety is recognized as a normal psychological reaction of those caring for cancer patients. However, anxiety disorders in caregivers may interfere with their care-giving role and require further clinical attention. Objectives: To determine the prevalence and associated factors of anxiety disorders among caregivers of breast cancer patients receiving oncologic treatment in Kuala Lumpur Hospital. Methodology: A cross-sectional study was conducted on 130 caregiver-patient dyads, recruited by non-random sampling at Kuala Lumpur Hospital. Data were collected in 2 stages: 1) the caregivers were screened for psychological distress using the Depression, Anxiety, Stress, Scale (DASS-21) while other related factors for the patients and their caregivers were obtained; 2) the identified distressed caregivers (n=64) were then administered the Mini International Neuropsychiatric Interview (MINI) to diagnose anxiety disorders. Results: A total of 11.5% (n=15) of the caregivers reported suffering from anxiety disorders. Bivariate analysis found duration of caregiving (OR=3.31; CI=2.21-11.93), shared caregiving (OR=4.07; CI=1.34-12.36), and patients’ treatment type (OR=3.42; CI=1.92-12.76) were significantly associated with anxiety disorders (p value <0.05), with shared caregiving and patient’s treatment type remaining significant using logistic regression (p value < 0.05, R2 = 0.255). Conclusions: Every one in ten of the caregivers in this study had a diagnosable anxiety disorder, associated with certain care-giving factors and patients’ treatment. This should alert clinicians to such risk and indicates psychological support needs for family caregivers.

    Genome-wide association study (GWAS) evidence has identified the metabotropic glutamate receptor 3 (GRM3) gene as a potential harbor for schizophrenia risk variants. However, previous meta-analyses have refuted the association between GRM3 single-nucleotide polymorphisms (SNPs) and schizophrenia risk. To reconcile these conflicting findings, we conducted the largest and most comprehensive meta-analysis of 14 SNPs in GRM3 from a total of 11 318 schizophrenia cases, 13 820 controls and 486 parent-proband trios. We found significant associations for three SNPs (rs2237562: odds ratio (OR)=1.06, 95% confidence interval (CI)=1.02-1.11, P=0.017; rs13242038: OR=0.90, 95% CI=0.85-0.96, P=0.016 and rs917071: OR=0.94, 95% CI=0.91-0.97, P=0.003). Two of these SNPs (rs2237562, rs917071) were in strong-to-moderate linkage disequilibrium with the top GRM3 GWAS significant SNP (rs12704290) reported by the Schizophrenia Working Group of the Psychiatric Genomics Consortium. We also found evidence for population stratification related to rs2237562 in that the 'risk' allele was dependent on the population under study. Our findings support the GWAS-implicated link between GRM3 genetic variation and schizophrenia risk as well as the notion that alleles conferring this risk may be population specific.

    INTRODUCTION: Selective serotonin reuptake inhibitors (SSRIs) are known for their sexual side effects. Different SSRIs may affect different areas of sexual function at different rates.
    AIMS: The study aimed to determine the prevalence of female sexual dysfunction (FSD), its clinical correlates, and association with 5HT2A (rs6311) single nucleotide polymorphisms (SNPs) in patients with major depressive disorder (MDD) who were on SSRI therapy.
    METHODS: This was a cross-sectional study on 95 female outpatients with MDD treated with SSRI. The patients were in remission as determined by Montgomery-Asberg Depression Rating Scale. Genomic DNA was isolated from buccal swabs and samples were processed using a real time polymerase chain reaction.
    MAIN OUTCOME MEASURES: The presence or absence of FSD as measured by the Malay Version of Female Sexual Function Index and 5HT2A-1438 G/A (rs6311) SNP.
    RESULTS: The overall prevalence of FSD was 32.6%. After controlling for age, number of children, education level, total monthly income, SSRI types, and SSRI dosing, being employed significantly enhanced FSD by 4.5 times (odds ratio [OR] = 4.51; 95% confidence interval [CI] 1.00, 20.30; P = 0.05). Those having marital problems were 6.7 times more likely to have FSD (OR = 6.67; 95% CI 1.57, 28.34). 5HT2A-1438 G/A (rs6311) SNP was not significantly associated with FSD.
    CONCLUSION: There was no significant association between FSD and the 5HT2A (rs6311) SNP in patients with MDD on SSRI therapy. Employment status and marital state were significantly associated with FSD among these patients.

    INTRODUCTION: Growing evidence suggesting that dietary intakes of adolescents are generally of poor quality but not adequately assessed in relation to the early manifestation of non-communicable diseases. This study aimed; (1) to examine tracking of an empirical dietary pattern (DP) linked to cardiometabolic risk factors and, (2) to assess prospective relationships between a DP characterised by high intakes of dietary energy density (DED) and added sugar, and cardiometabolic risk factors, non-alcoholic fatty liver disease (NAFLD), carotid intima-medial thickness (CIMT) and mental well-being during adolescence.

    METHODS AND ANALYSIS: The PUTRA-Adol is a prospective follow-up study that builds up from 933 Malaysian adolescents who were initially recruited from three southern states in Peninsular Malaysia in 2016 (aged 13 years then). Two sessions are planned; the first session will involve the collection of socio-economy, physical activity, dietary intakes, mental well-being, body image, risk taking behaviour, sun exposure, family functioning and menstrual (in women) information. The second session of data collection will be focused on direct assessments such as venesection for blood biochemistry, anthropometry and ultrasonography imaging of liver and bilateral carotid arteries. Z-scores for an empirical DP will be identified at 16 years using reduced rank regression. Multilevel modelling will be conducted to assess the tracking of DP and prospective analysis between the DP, cardiometabolic health, NAFLD, CIMT and mental well-being.

    ETHICS AND DISSEMINATION: Ethical approval for the conduct of this follow-up study was obtained from the Universiti Putra Malaysia's Ethics Committee for Research Involving Human Subjects (JKEUPM) (Reference number: JKEUPM-2019-267). The findings from this study will be disseminated in conferences and peer-reviewed journals.

    DISCUSSION: The findings gathered from this study will provide evidence on prospective relationships between DPs, cardiometabolic risk factors, NAFLD, early atherosclerosis and mental well-being and that it may be mediated particularly DED and added sugar during adolescence.

    The study was initiated with two major purposes: investigating the role of isomalt (GIQ9) as a pharmaceutical carrier for solid self-nanoemulsifying drug delivery systems (S-SNEDDSs) and improving the oral bioavailability of lipophilic curcumin (CUN). GIQ9 has never been explored for solidification of liquid lipid-based nanoparticles such as a liquid isotropic mixture of a SNEDDS containing oil, surfactant and co-surfactant. The suitability of GIQ9 as a carrier was assessed by calculating the loading factor, flow and micromeritic properties. The S-SNEDDSs were prepared by surface adsorption technique. The formulation variables were optimized using central composite design (CCD). The optimized S-SNEDDS was evaluated for differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), microscopy, dissolution and pharmacokinetic studies. The S-SNEDDS showed a particle size, zeta potential and PDI of 97 nm, -26.8 mV and 0.354, respectively. The results of DSC, XRD, FTIR and microscopic studies revealed that the isotropic mixture was adsorbed onto the solid carrier. The L-SNEDDS and S-SNEDDS showed no significant difference in drug release, indicating no change upon solidification. The optimized S-SNEDDS showed 5.1-fold and 61.7-fold enhancement in dissolution rate and oral bioavailability as compared to the naïve curcumin. The overall outcomes of the study indicated the suitability of GIQ9 as a solid carrier for SNEDDSs.
