    We investigated the effects of honey and its methanol and ethyl acetate extracts on inflammation in animal models. Rats' paws were induced with carrageenan in the non-immune inflammatory and nociceptive model, and lipopolysaccharide (LPS) in the immune inflammatory model. Honey and its extracts were able to inhibit edema and pain in inflammatory tissues as well as showing potent inhibitory activities against NO and PGE(2) in both models. The decrease in edema and pain correlates with the inhibition of NO and PGE(2). Phenolic compounds have been implicated in the inhibitory activities. Honey is potentially useful in the treatment of inflammatory conditions.

    Family planning is an important practice for women as it can help to improve financial and social status. Unwanted pregnancy has negative effects for husband and financial. However, couples married at a late age may not practice family planning because they want to have kids. The aims of this study were to determine the prevalence, factors associated with
    husband’s socio demography and decision making in family planning practices among women in reproductive age who attended a polyclinic in Serdang, Malaysia. A cross sectional study was conducted on 245 women with a systematic random sampling. Descriptive analysis, Fisher exact and Chi-square tests were conducted to identify the influence of husband’s socio demographic factors and decision making in family planning practices. The prevalence of family planning practices among married women was moderate (53.9%). Family planning practices among women showed significant relationship with the husband’s socio demography which were husband’s race (p = 0.018), religion (p = 0.008) and making decision in family planning (p = 0.002). The husband’s socio demography showed a significant relationship with the prevalence of the wife practicing family planning. This clearly indicates that the husband is the individual that influence the wife to use contraceptive method. Decision making in family planning by both the husband and wife is important in choosing to use contraceptive method. Health promotion in the concept of health education for male contraceptive method such as pamphlet and booklet is important to promote husband involvement in family planning.

    External laryngeal trauma is a rather rare occurrence, and comprises a varying severity of injuries. Every laryngeal injury is unique and the management can be invariably complex. For the most severe forms of external laryngeal trauma, reparative procedures and laryngeal stenting (after control of the airway) are considered standard treatment. We present a case of a complex laryngeal trauma with extensive loss of tracheal cartilage and soft tissues which was treated with total laryngectomy.

    Microtia comprises a spectrum of congenital malformation characterized by partial deformities of the auricular components to complete absence of pinna. Surgical reconstructions of this anomaly are often complex and technically challenging. Infection, hematoma, and skin necrosis with resultant exposed cartilage graft tend to occur in the early phase of post-operative care. Herein, we report a case of a spontaneous auricular abscess with exposed cartilage framework 20 years following rib cartilage reconstruction. To our knowledge, this is the first case of such an occurrence. The treatment options are discussed, along with the review of the literature.

    This paper proposes a small sized, low-cost multiband monopole antenna which can cover the WiMAX bands and C-band. The proposed antenna of 20 × 20 mm(2) radiating patch is printed on cost effective 1.6 mm thick fiberglass polymer resin dielectric material substrate and fed by 4 mm long microstrip line. The finite element method based, full wave electromagnetic simulator HFSS is efficiently utilized for designing and analyzing the proposed antenna and the antenna parameters are measured in a standard far-field anechoic chamber. The experimental results show that the prototype of the antenna has achieved operating bandwidths (voltage stand wave ratio (VSWR) less than 2) 360 MHz (2.53-2.89 GHz) and 440 MHz (3.47-3.91 GHz) for WiMAX and 1550 MHz (6.28-7.83 GHz) for C-band. The simulated and measured results for VSWR, radiation patterns, and gain are well matched. Nearly omnidirectional radiation patterns are achieved and the peak gains are of 3.62 dBi, 3.67 dBi, and 5.7 dBi at 2.66 GHz, 3.65 GHz, and 6.58 GHz, respectively.

    Gelam honey exerts anti-inflammatory and antioxidant activities and is thought to have potent effects in reducing infections and healing wounds. The aim of this study was to investigate the effects of intravenously-injected Gelam honey in protecting organs from lethal doses of lipopolysaccharide (LPS). Six groups of rabbits (N = 6) were used in this study. Two groups acted as controls and received only saline and no LPS injections. For the test groups, 1 mL honey (500 mg/kg in saline) was intravenously injected into two groups (treated), while saline (1 mL) was injected into the other two groups (untreated); after 1 h, all four test groups were intravenously-injected with LPS (0.5 mg/kg). Eight hours after the LPS injection, blood and organs were collected from three groups (one from each treatment stream) and blood parameters were measured and biochemical tests, histopathology, and myeloperoxidase assessment were performed. For survival rate tests, rabbits from the remaining three groups were monitored over a 2-week period. Treatment with honey showed protective effects on organs through the improvement of organ blood parameters, reduced infiltration of neutrophils, and decreased myeloperoxidase activity. Honey-treated rabbits also showed reduced mortality after LPS injection compared with untreated rabbits. Honey may have a therapeutic effect in protecting organs during inflammatory diseases.

    Monocytes and macrophages are part of the first-line defense against bacterial, fungal, and viral infections during host immune responses; they express high levels of proinflammatory cytokines and cytotoxic molecules, including nitric oxide, reactive oxygen species, and their reaction product peroxynitrite. Peroxynitrite is a short-lived oxidant and a potent inducer of cell death. Honey, in addition to its well-known sweetening properties, is a natural antioxidant that has been used since ancient times in traditional medicine. We examined the ability of Gelam honey, derived from the Gelam tree (Melaleuca spp.), to scavenge peroxynitrite during immune responses mounted in the murine macrophage cell line RAW 264.7 when stimulated with lipopolysaccharide/interferon-γ (LPS/IFN-γ) and in LPS-treated rats. Gelam honey significantly improved the viability of LPS/IFN-γ-treated RAW 264.7 cells and inhibited nitric oxide production-similar to the effects observed with an inhibitor of inducible nitric oxide synthase (1400W). Furthermore, honey, but not 1400W, inhibited peroxynitrite production from the synthetic substrate 3-morpholinosydnonimine (SIN-1) and prevented the peroxynitrite-mediated conversion of dihydrorhodamine 123 to its fluorescent oxidation product rhodamine 123. Honey inhibited peroxynitrite synthesis in LPS-treated rats. Thus, honey may attenuate inflammatory responses that lead to cell damage and death, suggesting its therapeutic uses for several inflammatory disorders.

    Any foreign body in the paranasal sinuses can cause chronic complications. It is therefore important to remove these foreign bodies meticulously. Various approaches are available to accomplish this. This article is a case report of a patient who had gutta-percha as a foreign body in left maxillary sinus, after a gutta-percha point had been used to trace a sinus to confirm that it was an oroantral fistula. Traditional surgical approaches to the maxillary sinus require invasive techniques, such as radical antrostomy and the Caldwell-Luc approach. These may result in further complications and morbidity. The gutta-percha point in this case report was removed endoscopically in an otolaryngology clinic with local anaesthesia using a sublabial antroscopy. There is only one case reported in the dental literature regarding the endoscopically-assisted technique for removal of displaced gutta-percha using the sublabial antroscopy approach (Yura S, Ohga N, Ooi K, Izumiyama Y. Procedure of endoscopic removal of a gutta-percha point in maxillary sinus mucosa by ultrathin arthroscope.

    Pulmonary hypertension in pregnancy is a rare condition but is associated with a high mortality. We report the case of a 29 year old female in early pregnancy with Protein C and S deficiency with recurrent deep venous thrombosis and pulmonary embolism and subsequent secondary pulmonary hypertension. The patient was counselled and consented for termination of pregnancy with tubal sterilization. She was administered continuous spinal anaesthesia with invasive monitoring. The successful anaesthetic management of this condition is described.

    Around June 2020, many institutions restarted full operating schedules to clear the backlog of postponed surgeries because of the first wave in the COVID-19 pandemic. In an online survey distributed among anaesthestists in Asian countries at that time, most of them described their safety concerns and recommendations related to the supply of personal protective equipment and its usage. The second concern was related to pre-operative screening for all elective surgical cases and its related issues. The new norm in practice was found to be non-standardized and involved untested devices or workflow that have since been phased out with growing evidence. Subsequent months after reinstating full elective surgeries tested the ability of many hospitals in handling the workload of non-COVID surgical cases together with rising COVID-19 positive cases in the second and third waves when stay-at-home orders eased.

    With the increasing number of COVID-19 cases and related deaths worldwide, we decided to share the development of this condition in Singapore and Malaysia. First few cases were diagnosed in the two countries at the end of January 2020, and the numbers have surged to thousands by end of March 2020. We will focus on strategies adopted by the government and also the Orthopaedic community of the two countries up till the beginning of April 2020. We hope that by sharing of relevant information and knowledge on how we are managing the COVID-19 condition, we can help other communities, and health care workers to more effectively overcome this pandemic.

    A 5-year retrospective survey of anaesthesia for caesarean section for mild/moderate and severe preeclampsia was performed, covering the period between 1 January 1996 and 31 December 2000. One hundred and twenty-one cases of non-labouring preeclamptic patients receiving spinal or epidural anaesthesia for caesarean section were included for analysis. Comparisons were made of the lowest blood pressures recorded before induction of anaesthesia, during the period from induction to delivery and the period from delivery to the end of operation. The decreases in blood pressure were similar after spinal and epidural anaesthesia. The use of intravenous fluids and ephedrine were also comparable in the two anaesthetic groups. There was no difference in maternal or neonatal outcome. Our result supports the use of spinal anaesthesia in preeclamptic women.

    INTRODUCTION: Urinary citrate is a potent inhibitor of urinary crystallization that is freely filtered in the proximal tubule of the kidney. We aimed to investigate the effect of citrate supplementation with fresh lime juice on the urinary pH and calcium excretion level among healthy individuals compared with that of mist potassium citrate.

    METHOD: In this prospective, cross-over single-centre study, 50 healthy medical student volunteers were randomly allocated to two treatment arms. One arm was prescribed with potassium citrate, while the other arm received citrate supplementation with a home preparation of fresh lime juice. The urinary pH and calcium-to-creatinine ratio (uCa/uCr) were measured at baseline and after 7 days of treatment. This was followed by a washout period of 2 weeks, after which each participant crossed over to the other treatment arm, and the urinary measurements were repeated.

    RESULTS: Potassium citrate significantly increased the urinary pH among all participants, while fresh lime juice did not. Both fresh lime juice and potassium citrate reduced the uCa/uCr, although this effect was not significant.

    CONCLUSION: Fresh lime juice is not as effective as potassium citrate in improving the urinary pH and calcium excretion level of healthy individuals. Therefore, it should be used as an adjunct rather than an alternative to potassium citrate.

    This scoping review describes the research-based mindfulness intervention on anxiety, distress, and depression. The search strategy retrieved articles published in English from 2014 to 2019 and were retrieved across Scopus, Web of Science, Science Direct, CINAHL, and Google Scholar. The PRISMA-Scr checklist is a tool to evaluate the quality of the articles. The selection criteria initially included all original articles in English, with 1,527 that were related to mindfulness intervention for anxiety, distress, and depression. A total of 490 full texts were retrieved, and after the abstracts were reviewed, 124 full-text articles were included for eligibility, and the final eight studies were determined. The articles were reviewed and screened for relevance to mindfulness intervention in reducing anxiety, distress, and depression among those with chronic diseases. The results have shown that mindfulness intervention reduces anxiety, distress, and depression among patients with chronic diseases. The review contributes further insight into the fact that mindfulness intervention is also appropriate for other conditions to facilitate reducing psychological symptoms.

    BACKGROUND: Employees' work experience significantly impacts their cognition and workplace actions. Anger and negative affectivity are two personality traits that have been linked to workplace deviant behavior conduct.

    OBJECTIVE: This study aimed to empirically analyze the deviant workplace behavior and its antecedents among Malaysian nurses in public hospitals.

    METHODS: A cross-sectional design was employed in this study. The survey questionnaires were distributed proportionately to staff nurses in six government hospitals in 2020, with a total of 387 nurses selected using a simple random sampling. Partial Least Squares Structural Equation Modeling (PLS-SEM) was used for data analysis.

    RESULTS: Trait anger triggered deviant workplace behavior in Malaysian nurses, thus supporting the argument that the personality trait could increase deviant behavior (β = 0.245, p = 0.000). At the same time, there was no evidence that negative affectivity could influence deviant behavior in the workplace among nurses in selected public hospitals in Malaysia (β = 0.074, p = 0.064).

    CONCLUSION: The Malaysian nurses had positive affectivity, related to positive emotions like happiness, work interest, and attentiveness. On the other hand, the nurses were suffering from high levels of emotional tiredness. Further research should highlight a deeper understanding of Malaysian nurses' work experiences and workplace stress affecting their physical and mental health.

    Quorum sensing is a term that describes an environmental sensing system that allows bacteria to monitor their own population density which contributes significantly to the size and development of the biofilm. Many gram negative bacteria use N-acyl-homoserine lactones as quorum sensing signal molecules. In this study, we sought to find out if the biofilm formation among clinical isolates of Acinetobacter spp. is under the control of autoinducing quorum sensing molecules.

    Malaysian Gelam honey has anti-inflammatory and antibacterial properties, a high antioxidant capacity, and free radical-scavenging activity. Lipopolysaccharide (LPS) stimulates immune cells to sequentially release early pro- and anti-inflammatory cytokines and induces the synthesis of several related enzymes. The aim of this study was to investigate the effect of the intravenous injection of honey in rats with LPS-induced endotoxemia. The results showed that after 4h of treatment, honey reduced cytokine (tumor necrosis factor-α, interleukins 1β, and 10) and NO levels and increased heme oxygenase-1 levels. After 24h, a decrease in cytokines and NO and an increase in HO-1 were seen in all groups, whereas a reduction in HMGB1 occurred only in the honey-treated groups. These results support the further examination of honey as a natural compound for the treatment of a wide range of inflammatory diseases.
