Severe hyponatraemia is defined as a sodium level of less than 120 mEq/L, and it is frequently accompanied by neurological symptoms like coma, convulsions, respiratory arrest, and death. Clinical cardiac toxicity from hyponatremia, such as bradyarrhythmia, is extremely rare. In this article, we present a case of acute severe hyponatraemia that induced unstable bradyarrhythmia and led to refractory bradycardia, which did not improve despite receiving treatment in accordance with the standard Advanced Cardiovascular Life Support protocol. The patient’s bradyarrhythmia has completely resolved with the administration of 3% hypertonic saline, which restored her sodium levels. Due to the possibility that severe hyponatremia may contribute to the aetiology of cardiac malfunction, this case raises awareness about the significance of closely monitoring electrocardiograms and telemetry in patients with severe hyponatremia.

Methods: Patients with severe kyphoscoliosis having coronal Cobb angle >90° were applied with modified halo-pelvic Ilizarov distraction assembly preoperatively. The modified assembly consisted of a pelvic component and halo ring, and distraction was given at the rate of 2–3 mm/day for 6–12 weeks. Complete clinical assessments along with pulmonary function tests were performed, and scoliosis series X-ray images were assessed for coronal and sagittal Cobb angle and other spinopelvic parameters before applying the assembly and during 2 years of follow-up. Results: Thirty-four patients (age, 9–27 years; male/female ratio of 18:16) were included. The coronal and sagittal Cobb angles were 116°±16.2° and 84°±28.3°, respectively. Correction rates obtained through modified halo-pelvic assembly were nearly 52% (p=0.001) in coronal and 40% (p=0.001) in sagittal Cobb angles, with improvement in height (p=0.001). Apical vertebral translation and coronal balance were also improved significantly (p=0.001). Further improvements in all the parameters were obtained after definitive surgery, with improvements in the forced expiratory volume in 1 second (p =0.002) and forced vital capacity (p=0.001). Conclusions Our modified halo-pelvic Ilizarov distraction assembly can achieve good correction in severe spinal deformities without significant risk to neurology, has fewer complications, and promotes good patient compliance.

Medical implants are normally used in clinical practice to treat most orthopaedics situations involving bone fractures, deformities, dislocation, and lengthening. It should be noted that specific measures regarding biomechanical and biomaterial characteristics are required for a successful post-surgery procedure. Biomechanical evaluations on the medical implants could be performed by utilising computer and engineering technology. One of them is in silico studies using finite element method that could be simulated in high-performance computer. However, various assumptions are required in computer simulation, such as the constraints on data input and computer resources. This review paper discusses current approaches of constructing a finite element model of human bone with specific material properties for upper limb such as the shoulder joint, humerus, elbow joint, radius and wrist joint. Previous related literatures were reviewed from selected keywords and search engines. To narrow the literature search in this study, inclusion and exclusion criteria of the literature searching were applied. We looked at the current level of knowledge in this field and offered recommendations for future study. In conclusion, studies from previous literature have demonstrated several ways for developing mathematical models and simulating medical implants.

Aims: Acaudina molpadioides is a highly valued sea cucumber that is distributed on the muddy shores on the west coast of Peninsular Malaysia and is considered a local delicacy. Carnobacterium maltaromaticum is a type of lactic acid bacteria commonly found in meat, fish and dairy products and is usually isolated from the intestine of aquatic animals. It is scarcely reported from the intestine of A. molpadioides. This species is known to be pathogenic in fish but unknown in humans. The aim of this study was to isolate and characterize C. maltaromaticum from the intestine of A. molpadioides. Methodology and results: Using standard methods, the strains were tested for their biochemical and carbohydrate properties, antibiotic sensitivity tests, temperature sensitivity tests and molecular identification. A total of 1642 isolates were obtained, out of which three strains were chosen as they were catalase-negative, Gram-positive bacilli, negative to IMViC tests, γ-hemolysis, and positive to lactose and glucose tests. Molecular identification was made to strain AM47e and 16S rRNA genes sequence showed 99.93% similar to C. maltaromaticum. The sequence was submitted to GenBank as Carnobacterium maltaromaticum (Accession No: MZ 934727). The optimum growth temperature for the strains was 37°C and the antibiotic susceptibility showed they were sensitive to tetracycline, ampicillin and meropenem. Conclusion, significance and impact of study In conclusion, C. maltaromaticum can be isolated from the intestine of A. molpadioides with the potential of the probiotic applications and less potential vulnerability for consumers.

Introduction: Poor waste management led to mosquito breeding grounds. Previous research found that construction sites are the mosquito breeding area thus it’s important to understand how construction sites affect mosquito breeding. Methods: This study utilized a prospective study to determine the characteristic of breeding preference in residential construction sites. On-field breeding preference survey was conduct in the selected project site in 12 weeks (1st October 2021 until 31st December 2021). Wet container inspection was carried out according to types of the residential construction building and progress of the site. All possible wet materials and containers was inspected and record accordingly in the form during the surveillance. Results: Result shows that the most preferred containers found was building floor (41.68%), others such as planter box that use for landscape purpose, drainage system, building mould and lift wells. The results of the research indicate that prospective containers with water and breeding sites at high rise construction sites were found to be more than those at low rise construction sites. Conclusion: Overall, substantially fewer water containers were discovered in low rise projects compared to high rise projects. Construction management need encourage all the workers to do best management practice such as proper waste disposal and removal of the water and possible wet container and conduct awareness among the workers.

Purpose: Despite the significant role of varicocele in the pathogenesis of male infertility, the impact of varicocele repair (VR) on conventional semen parameters remains controversial. Only a few systematic reviews and meta-analyses (SRMAs) have evaluated the impact of VR on sperm concentration, total motility, and progressive motility, mostly using a before-after analytic approach. No SRMA to date has evaluated the change in conventional semen parameters after VR compared to untreated controls. This study aimed to evaluate the effect of VR on conventional semen parameters in infertile patients with clinical varicocele compared to untreated controls. Materials and Methods: A literature search was performed using Scopus, PubMed, Embase, and Cochrane databases following the Population Intervention Comparison Outcome (PICOS) model (Population: infertile patients with clinical varicocele; Intervention: VR [any technique]; Comparison: infertile patients with clinical varicocele that were untreated; Outcome: sperm concentration, sperm total count, progressive sperm motility, total sperm motility, sperm morphology, and semen volume; Study type: randomized controlled trials and observational studies). Results: A total of 1,632 abstracts were initially assessed for eligibility. Sixteen studies were finally included with a total of 2,420 infertile men with clinical varicocele (1,424 patients treated with VR vs. 996 untreated controls). The analysis showed significantly improved post-operative semen parameters in patients compared to controls with regards to sperm concentration (standardized mean difference [SMD] 1.739; 95% CI 1.129 to 2.349; p<0.001; I2=97.6%), total sperm count (SMD 1.894; 95% CI 0.566 to 3.222; p<0.05; I2=97.8%), progressive sperm motility (SMD 3.301; 95% CI 2.164 to 4.437; p<0.01; I2=98.5%), total sperm motility (SMD 0.887; 95% CI 0.036 to 1.738; p=0.04; I2=97.3%) and normal sperm morphology (SMD 1.673; 95% CI 0.876 to 2.470; p<0.05; I2=98.5%). All the outcomes showed a high inter-study heterogeneity, but the sensitivity analysis showed that no study was sensitive enough to change these results. Publication bias was present only in the analysis of the sperm concentration and progressive motility. No significant difference was found for the semen volume (SMD 0.313; 95% CI -0.242 to 0.868; I2=89.7%). Conclusions This study provides a high level of evidence in favor of a positive effect of VR to improve conventional semen parameters in infertile men with clinical varicocele. To the best of our knowledge, this is the first SRMA to compare changes in conventional semen parameters after VR with changes in parameters of a control group over the same period. This is in contrast to other SRMAs which have compared semen parameters before and after VR, without reference to a control group. Our findings strengthen the available evidence and have a potential to upgrade professional societies’ practice recommendations favoring VR to improve conventional semen parameters in infertile men.

Purpose: Varicocele is a common problem among infertile men. Varicocele repair (VR) is frequently performed to improve semen parameters and the chances of pregnancy. However, there is a lack of consensus about the diagnosis, indications for VR and its outcomes. The aim of this study was to explore global practice patterns on the management of varicocele in the context of male infertility. Materials and Methods: Sixty practicing urologists/andrologists from 23 countries contributed 382 multiple-choice-questions pertaining to varicocele management. These were condensed into an online questionnaire that was forwarded to clinicians involved in male infertility management through direct invitation. The results were analyzed for disagreement and agreement in practice patterns and, compared with the latest guidelines of international professional societies (American Urological Association [AUA], American Society for Reproductive Medicine [ASRM], and European Association of Urology [EAU]), and with evidence emerging from recent systematic reviews and meta-analyses. Additionally, an expert opinion on each topic was provided based on the consensus of 16 experts in the field. Results: The questionnaire was answered by 574 clinicians from 59 countries. The majority of respondents were urologists/ uro-andrologists. A wide diversity of opinion was seen in every aspect of varicocele diagnosis, indications for repair, choice of technique, management of sub-clinical varicocele and the role of VR in azoospermia. A significant proportion of the responses were at odds with the recommendations of AUA, ASRM, and EAU. A large number of clinical situations were identified where no guidelines are available. Conclusions This study is the largest global survey performed to date on the clinical management of varicocele for male infertility. It demonstrates: 1) a wide disagreement in the approach to varicocele management, 2) large gaps in the clinical practice guidelines from professional societies, and 3) the need for further studies on several aspects of varicocele management in infertile men.

Introduction: With the rising number of COVID-19 cases in Malaysia and the overwhelming strain on the tertiary healthcare system, home isolation has been introduced by the Ministry of Health Malaysia to reduce the admission of patients with mild COVID-19 to tertiary and low-risk quarantine centres. COVID-19 assessment centres (CACs) have been set up to provide initial assessment, triaging and monitoring of patients with COVID-19 prior to and during their home isolation. In this study, we aimed to share our experience in setting up CACs in Selangor, Malaysia. Methods: We described the steps taken in developing assessment tools and guidelines for assisting healthcare providers in safely monitoring patients with COVID-19 undergoing home isolation. Results: A total of 26,826 patients were clinically assessed from 1 to 28 February 2021 in various CACs in the state. The majority of the cases seen in the CACs were under category (CAT) 1 and 2.Only 0.2% (n=53) of the cases were categorised as severe COVID-19 (CAT 3 and above). Conclusion CACs coordinated by primary care providers play an important role in triaging,assessing and monitoring patients with COVID-19 undergoing home isolation in the community.There needs to be a better partnership between various stakeholders and the private healthcare sector to improve the services. The usage of a pulse oximeter in home monitoring of all patients withCOVID-19 in Selangor needs to be seriously considered.

Speech and language skills are among the crucial components in determining cochlear implant habilitation outcomes. The purpose of this study was to investigate speech and language skills of Malay cochlear implant children using a developmental scale questionnaire and to identify the demographic factors that contribute to their performance. This study involved 26 children recruited from the National Cochlear Implant Program under the Malaysian Ministry of Health with chronological ages between 33 to 99 months (mean=72, SD=18.9), implant ages between 18 to 71 months (mean=40, SD=13.5) and hearing ages between 13 to 48 months (mean=30, SD=10.5). The instrument used was The Integrated Scale of Development-Malay version 2 (ISD-Mv2). The questionnaires were given to the parents or caregivers followed with by a phone call interview later. Results from the study showed that only 9 subjects (35%) were able score on the ISD-Mv2 equally or higher than their hearing age. From the six components in the ISD-Mv2, cognitive was scored the highest with 96.79% meanwhile expressive language was the lowest with 76.21%. Pearson correlation test revealed strong positive correlation between audition-receptive language (r=0.554, p<0.05) and cognitive–social communication/ pragmatic (r= 0.625, p<0.05). Speech and language performance of children with demographic factors did not show significant differences. The findings suggests that majority of the Malay cochlear implant children demonstrated delayed speech and language performance as compared to normal hearing children.

Introduction: The incidence and complications of hyperlipidemia associated co-morbidities and mortalities are grossly increasing globally. Intervention with natural products preparation has been identified as an alternative for the management of hyperlipidaemia and its related cardiovascular complications. This study investigated the anti-hyperlipidaemic activities of a mixture of Zinger officinale, Allium sativum, Citrus lemon, honey, and Malus domestica vinegar (ZACAH) extracts in in Sprague Dawley (SD) rats fed with high cholesterol diet. Methods: Thirty-six male SD rats were randomly distributed into 6 groups, including normal chow diet-fed (NC), high cholesterol diet (HCD), HCD+ Simvastatin (standard drug) while the remaining three groups were fed with HCD + ZACAH extracts at different doses (1, 3 and 5mg/kg body weight) for 18 weeks. Simvastatin at 10 mg/kg of bodyweight was used as control. High-performance liquid chromatography (HPLC) was used to determine phenolic compounds present in ZACAH extracts, elastase inhibitory assay was determined using spectrometric with a substrate (N-Succ-(Ala)3-pnitroanilide (SANA) while 2,2-diphenyl-1-picrylhydrazyl (DPPH) was performed based by the method described by Blois, 1958. Results: In vitro; ZACAH extracts had oxygen radical absorbance capacity (ORAC) value of 2000 µmol TE/100 mL, total phenolic content (TPC) of 7537 ± 54.5%, DPPH free radical scavenging activity of 27.34 ± 2.71%, elastase inhibitory assay of 29.29 ± 1.65% and lipoxygenase inhibitory assay of 98.58 ± 1.42%. In vivo, ZACAH extracts showed decreased bodyweight, adipose tissue, improved lipid profiles and hepatic biochemical enzymes. Conclusion: These results suggested that ZACAH extracts supplementation improved hyperlipidaemia in SD rats and might be a promising adjuvant for the treatment of hyperlipidaemia.
