    Alcohol use disorder (AUD) is characterized by compulsive binge alcohol intake, leading to various health and social harms. Protein Kinase C epsilon (PKCε), a specific family of PKC isoenzyme, regulates binge alcohol intake, and potentiates alcohol-related cues. Alcohol via upstream kinases like the mammalian target to rapamycin complex 1 (mTORC1) or 2 (mTORC2), may affect the activities of PKCε or vice versa in AUD. mTORC2 phosphorylates PKCε at hydrophobic and turn motif, and was recently reported to be associated with alcohol-seeking behavior, suggesting the potential role of mTORC2-PKCε interactions in the pathophysiology of AUD. mTORC1 regulates translation of synaptic proteins involved in alcohol-induced plasticity. Hence, in this article, we aimed to review the molecular composition of mTORC1 and mTORC2, drugs targeting PKCε, mTORC1, and mTORC2 in AUD, upstream regulation of mTORC1 and mTORC2 in AUD and downstream cellular mechanisms of mTORCs in the pathogenesis of AUD.

    The use of manual stretching procedures has become more prevalent in cardiorespiratory physiotherapy to improve pulmonary functions. However, limited evidence exists regarding evaluation of their effectiveness. The study aimed to determine the impact of Intercostal (IC) stretch in improving the dynamic pulmonary function parameters (Forced Expiratory Volume in the first second (FEV1), Forced Vital Capacity (FVC) and FEV1/FVC % and respiratory rate among healthy adults. Thirty healthy male subjects were recruited based on inclusion and exclusion criteria. Subjects were assigned to the experimental group and the control group through random sampling method. In the experimental group, subjects underwent IC stretch for ten breaths on the inspiratory phase of the respiratory cycle with breathing control exercises in semi recumbent position, while in the control group, breathing control exercises alone were performed in the semi recumbent position. The results of the study showed, FEV1/FVC % in the experimental group significantly improved with P=0.017 (p<0.05) than the control group, which means IC stretch increased lung volume and lead to improved lung function. This study suggested the IC stretching with breathing control may be more effective in improving dynamic lung parameters especially FEV1/FVC % than breathing control alone.
  4. The Neurobiology and Psychiatric Perspective of Vaginismus: Linking the Pharmacological and Psycho-Social Interventions

    Vaginismus is an involuntary muscle contraction of the outer third of vaginal barrel causing sexual penetration almost impossible. It is generally classified under sexual pain disorder (SPD). In Diagnostic and Statistical Manual, 5th edition (DSM-5), it is classified under the new rubric of Genito-Pelvic Pain/Sexual Penetration Disorder. This fear-avoidance condition poses an ongoing significant challenge to the medical and health professionals due to the very demanding needs in health care despite its unpredictable prognosis. The etiology of vaginismus is complex: through multiple biopsycho- social processes, involving bidirectional connections between pelvic-genital (local) and higher mental function (central regulation). It has robust neural and psychological-cognitive loop feedback involvement. The internal neural circuit involves an inter-play of at least two-pathway systems, i.e. both "quick threat assessment" of occipital-limbic-occipital-prefrontal-pelvic-genital; and the chronic pain pathways through the genito-spinothalamic-parietal-pre-frontal system, respectively. In this review, a neurobiology root of vaginismus is deliberated with the central role of an emotional-regulating amygdala, and other neural loop, i.e. hippocampus and neo-cortex in the core psychopathology of fear, disgust, and sexual avoidance. Many therapists view vaginismus as a neglected art-and-science which demands a better and deeper understanding on the clinico-pathological correlation to enhance an effective model for the bio-psycho-social treatment. As vaginismus has a strong presentation in psychopathology, i.e. fear of penetration, phobic avoidance, disgust, and anticipatory anxiety, we highlighted a practical psychiatric approach to the clinical management of vaginismus, based on the current core knowledge in the perspective of neuroscience.

    Sexuality is an important dimension in human beings as a form of expression of individuality. For many decades, sexual functioning has been a neglected area among patients suffering from schizophrenia. It was a presumption that patients with schizophrenia could be asexual and this could be secondary to overwhelming situations of delusion, hallucination, hostility and negative symptoms among others. The deficient in sexual functioning are due to innate factors, i.e. negative symptoms (apathy, avolition and amotivation) and also as a result of prefrontal dysfunction, i.e. inability to plan and execute meaningful relationship. Adverse effects of the psychopharmacological agents, especially the typical antipsychotics, e.g. dystonia, excessive sedation and hyperprolactinemia may interfere with patients' sexual activity. In this review, we highlight the neurobiology of schizophrenia in the context of understanding sexual functioning and to integrate the knowledge of dopamine-serotonin neurotransmitter's interaction and the receptors' target. Interventional approaches consist of psychopharmacological and psychosocial interventions. In the perspective of sexuality, we recommend atypical antipsychotic should be placed as the first line treatment for both drug naïve patients and also to patients who are already receiving psychopharmacological agents in consideration for a drug-switch from typical to atypical antipsychotics. Aripiprazole, clozapine, olanzapine and quetiapine exert benefits in terms of sexual functioning recovery due to their atypical mechanism of action. However, the potential adverse effect like metabolic syndrome should be adequately managed to prevent negative consequences. Psychosocial interventions, i.e. psychoeducation, destigmatization, supportive psychotherapy and psychiatric rehabilitation also play a crucial role in the management. In conclusion, restoration of sexual function is an achievable recovery target in patients with schizophrenia through these biopsycho- social interventions.
  6. Co-Morbid Erectile Dysfunction (ED) and Antidepressant Treatment in a Patient - A Management Challenge?
    Zainol M, Sidi H, Kumar J, Das S, Ismail SB, Hatta MH, et al.
    Curr Drug Targets, 2019;20(2):182-191.
    PMID: 28302034 DOI: 10.2174/1389450118666170315110902
    Throughout the world, antidepressants (AD) and phosphodiesterase-5 inhibitors (PDE-5i) are the commonly prescribed psychopharmacological agents for treating patients with co-morbid mental health problem and sexual dysfunction (SD). The serotonergic and noradrenergic ADs, although effective, are not without any SD adverse-effects, especially erectile dysfunction (ED). ED is a failure to obtain a satisfactory erection for rewarding sexual coitus during the phases of male's sexual arousal. It is recognized as an important reason why non-adherence to treatment was observed in patients who were on AD. AD intervention caused remission to some of the pre- treatment psychopathology of ED. However, in many patients, AD potentially magnified the unwanted sexual sideeffects. This made the situation challenging for the mental health professional. These challenges are based on the complexity of ED, its etiology and the associated risk factors, which further add to its AD side-effect. The neuro-psychopharmacological basis for AD treatment selection was deliberated. Bio-psycho-social interventions are recommended at two pivotal stages. Firstly, a step should be taken for proper assessment (e.g. detailed history, psychosocial and laboratory investigations); and identify few modifiable risk factors for ED and associated mental health issues. Secondly, with guidance of an algorithm pathway, a practical intervention should include strategies such as dose reduction, augmentation or changing to an AD with lesser or no sexual adverse-effects. It is recommended that bupropion and mirtazepine to be prescribed when patients develop adverse sexual effects with serotonin selective reuptake inhibitor (SSRI), serotonin norepinephrine reuptake inhibitor (SNRI) and tricyclic antidepressant (TCA). Few suggestions which may be borne in mind are revising sexual scripts and improving sexual techniques, life-style modifications, psychotherapy and other nonpharmacological approaches which may be beneficial to both patients and their partners.
  7. Kratom and Future Treatment for the Opioid Addiction and Chronic Pain: Periculo Beneficium?
    Ismail I, Wahab S, Sidi H, Das S, Lin LJ, Razali R
    Curr Drug Targets, 2019;20(2):166-172.
    PMID: 28443503 DOI: 10.2174/1389450118666170425154120
    Kratom (Mitragyna speciosa), a naturally existing plant found in South-East Asia, is traditionally used as a herb to help elevate a person's energy and also to treat numerous medical ailments. Other than the analgesic property, kratom has been used as an agent to overcome opioid withdrawal as it contains natural alkaloids, i.e. mitragynine, 7-hydroxymitragynine, and MGM-9, which has agonist affinity on the opioid receptors, including mu (µ) and kappa (κ). The role of neural reward pathways linked to µ-opioid receptors and both dopaminergic and gamma-Aminobutyric acid (GABA)-ergic interneurons that express µ-opioid receptors were deliberated. However, kratom has been reported to be abused together with other illicit substances with high risk of potential addiction. There are also anecdotes of adverse effects and toxicity of kratom, i.e. tremor, fatigue, seizure, and death. Different countries have distinctive regulation and policy on the plantation and use of this plant when most of the countries banned the use of it because of its addiction problems and side effects. The aim of this review is to highlight on the potential use of kratom, unique 'herbs" as a substitution therapy for chronic pain and opioid addiction, based on the neurobiological perspective of pain and the underlying mechanism of actions of drug addiction.
  8. Understanding the Pathophysiology of Premature Ejaculation: Bridging the Link between Pharmacological and Psychological Interventions
    Yusof F, Sidi H, Das S, Midin M, Kumar J, Hatta MH
    Curr Drug Targets, 2018;19(8):856-864.
    PMID: 27993112 DOI: 10.2174/1389450117666161215161108
    Premature ejaculation (PE) is one of the commonest male sexual dysfunctions. It is characterized by ejaculation which occurs before or soon after vaginal penetration, which causes significant psychological distress to the individual, and his partner. The exact cause of PE is still unknown but several mechanisms are proposed, and these involve complex interactions of neurophysiological, psychosocial, and cognitive factors. We discuss the role of serotonin, nitric oxide, phosphodiesterase enzymes and other neurotransmitters. Treatment of PE tends to co-occur with other sexual difficulties, especially erectile dysfunction (ED). Treatment with selective serotonin reuptake inhibitors (SSRIs) and Dapoxitene are also discussed in detail. The treatment strategy requires a comprehensive holistic approach incorporating both combination of psychopharmacological agent and cognitive-behavioral therapy (CBT). The present review highlights the integration of the hypothalamic-neural and reverberating emotional circuit and discusses the etiology and treatment for patients with PE.
  9. Serotonin Selective Reuptake Inhibitors (SSRIs) and Female Sexual Dysfunction (FSD): Hypothesis on its Association and Options of Treatment
    Rappek NAM, Sidi H, Kumar J, Kamarazaman S, Das S, Masiran R, et al.
    Curr Drug Targets, 2018;19(12):1352-1358.
    PMID: 28025939 DOI: 10.2174/1389450117666161227142947
    Sexual dysfunctions are commonly seen in women on selective serotonin reuptake inhibitors (SSRIs). The complexities of female sexual functioning are reflected through modulation of inter- playing factors like the neuropsychophysiological factors, inter-personal and relationship issue, psychiatric co-morbidities and physical disorder. The incidence of SSRIs-induced FSD is difficult to estimate because of the potential confounding effects of SSRIs, presence of polypharmacy, marital effect, socio-cultural factors and due to the design and assessment problems in majority of the studies. The exact mechanism of FSD-induced SSRIs is unknown. It has been postulated that although SSRIs may modulate other neurotransmitter system such as nitric oxide (NO), noradrenergic and dopamine in inducing FSD. In the present review, we highlight current evidence regarding potential mechanism of SSRIs in causing FSD, which include low sexual desire (low libido), arousal difficulties (lack of lubrication), and anorgasmia. The specific association of FSD to SSRI use, has not been ellucidated. The relationship is dose-dependent, and may vary among the groups with respect to mechanism of serotonin and dopamine reuptake, induction of release of prolactin from the pituitary gland, anticholinergic side-effects, inhibition of NO synthesis and emotional-memory circuit encryption for sexual experiences. Various interventional strategies exist regarding the treatment of SSRI-induced FSD and this includes tolerance, titration dosage, substitution to another antidepressant drug and psychotherapy. There is a need of better understanding of SSRIs-induced FSD for better treatment outcome.
  10. Biological and psychological influences of cross sex hormone in transgender
    Ling LS, Sidi H, Lope RAR, Das S, Baharudin A
    Curr Drug Targets, 2018 May 11.
    PMID: 29749310 DOI: 10.2174/1389450119666180511161420
    Transgender is a complex state of bio-psycho-social dimension of human sexuality. It encompasses cognitive-emotional-behavior component that makes the person unique in his or her sexual expression. Transgender tend to use cross sex hormone in order to eradicate their secondary sexual characteristics and to facilitate the shift to their experienced gender. The common masculinising sex hormone use, i.e. Female to Male Treatment Options (FMTO) is testosterone and for feminising hormone i.e. Male to Female Treatment Options (MFTO) is a combination of estrogen with anti-androgen, respectively. Cross sex hormone, i.e. FMTO, or MFTO has biological and psychological influences on the transgender individuals. Nevertheless, cross sex hormone may also poses a range of side effect profiles, varies from the biological to psychosocial impact. The psychological impact can be paramount until it causes severe mental-health problems and even suicide. Numerous ranges of bio-psycho-social influence of cross-sex hormone were highlighted in this review as fundamental core knowledge in the art to know practice when dealing with the treatment options. In psychiatry, the change in the biological appearance may have great influence in the transgender individual, especially in the context of psychosocial and cultural perspective.
  11. The Bio-Psycho-Social Dimension in Women's Sexual Desire: 'Argumentum ad novitatem'
    Roslan NS, Jaafar NRN, Sidi H, Baharudin N, Kumar J, Das S, et al.
    Curr Drug Targets, 2019;20(2):146-157.
    PMID: 28641524 DOI: 10.2174/1389450118666170622090337
    Sexual desire includes complex motivation and drive. In the context of biological and cognitive- emotive state art of science, it is often a neglected field in medicine. In regard to the treatment, study on women's sexual function received less attention compared to the men's sexuality. In the past, this endeavor was relatively not well disseminated in the scientific community. Recently, there was a revolutionized surge of drug targets available to treat women with low sexual desire. It is timely to review the relevant biological approach, especially in the context of pharmacotherapy to understand this interesting clinical entity which was modulated by numerous interactive psychosocial inter-play and factors. The complex inter-play between numerous dimensional factors lends insights to understand the neural mechanism, i.e. the rewards centre pathway and its interaction with external psychosocialstimulus, e.g. relationship or other meaningful life events. The function of hormones, e.g. oxytocin or testosterone regulation was described. The role of neurotransmitters as reflected by the introduction of a molecule of flibenserin, a full agonist of the 5-HT1A and partial agonist of the D4 to treat premenopausal women with low sexual desire was deliberated. Based on this fundamental scientific core knowledge, we suggest an outline on know-how of introduction for sex therapy (i.e. "inner-self" and "outer-self") where the role of partner is narrated. Then, we also highlighted on the use of pharmacological agent as an adjunct scope of therapy, i.e. phosphodiasterase-5 (PDE-5) inhibitors and hormonal treatment in helping the patient with low sexual desire.
  12. Try to Remember: Interplay between Memory and Substance Use Disorder
    Mohamed RMP, Kumar J, Yap E, Mohamed IN, Sidi H, Adam RL, et al.
    Curr Drug Targets, 2019;20(2):158-165.
    PMID: 28641520 DOI: 10.2174/1389450118666170622092824
    Memories associated with substance use disorders, or substance-associated cues increase the likelihood of craving and relapse during abstinence. There is a growing consensus that manipulation of synaptic plasticity may reduce the strength of substance abuse-related memories. On the biological front, there are new insights that suggest memories associated with substance use disorder may follow unique neurobiological pathways that render them more accessible to pharmacological intervention. In parallel to this, research in neurochemistry has identified several potential candidate molecules that could influence the formation and maintenance of long-term memory. Drugs that target these molecules (blebbistatin, isradipine and zeta inhibitory peptide) have shown promise at the preclinical stage. In this review, we shall provide an overview of the evolving understanding on the biochemical mechanisms involved in memory formation and expound on the premise that substance use disorder is a learning disorder.
  13. The Novelty of Bupropion As a Dopaminergic Antidepressant for the Treatment of Adult Attention Deficit Hyperactive Disorder
    Deang KT, Sidi H, Zakaria H, Adam RL, Das S, Hatta NH, et al.
    Curr Drug Targets, 2019;20(2):210-219.
    PMID: 28494748 DOI: 10.2174/1389450118666170511145628
    Attention deficit hyperactive disorder (ADHD), a hyperactivity disorder prevalent among children may continue as an adulthood attention deficit. To date, treating an individual with an adult ADHD may be an arduous task as it involves numerous challenges, which include a need for high index of suspicion to diagnose this medical condition. Many psychiatric disorders masquerade as ADHD and delay the necessary assessment and proper treatment for this debilitating medical disorder. Adult ADHD is often misdiagnosed (or under diagnosed) due to the fact that this medical condition is being masked by the patients' high level of intellectual achievement. As the ADHD in adult persists, it may end-up with impairment in the personal-social-occupational function in which the management becomes a great challenge. The treatment of ADHD can be optimized by using various drugs targets agents like norepinephrine-dopamine reuptake inhibitor (NDRI), with or without psycho stimulants like methylphenidate, which is marketed as Ritalin. Bupropion, an NDRI has a novel effect on ADHD as the molecule exerts its effects by modulating the reward-pleasure mesolimbic dopaminergic system and at the same time regulates the elevating mood dimension of the noradrenergic neurotransmission. The role of Bupropion in the neural and psychopharmacological perspective treatment of ADHD was deliberated. The present review highlights the novel effects of Bupropion in ADHD treatment, together with the help of other successful bio-psycho-social measures. This may be of immense benefit to the psychiatrists for treating their patients.
  14. Subduing the Green-eyed Monster: Bridging the Psychopharmacological and Psychosocial Treatment Perspective in Understanding Pathological Jealousy
    Samad FDA, Sidi H, Kumar J, Das S, Midin M, Hatta NH
    Curr Drug Targets, 2019;20(2):201-209.
    PMID: 28675999 DOI: 10.2174/1389450118666170704142708
    Human being is not spared from a broad-ranged emotional state, including being jealous. Jealousy has both affective-cognitive and behavioural-evaluative dimension where the person perceives, or experiences a real threat on a valued relationship. As this complex emotion becomes irrational and not amenable to reason, it later transforms into a dangerously 'green-eyed monster'. This perilous situation which is viewed as pathological jealousy is a form of delusion, which is maintained by a fixed and false reasoning in an originally entrusted intimate relationship. Pathological jealousy is equally prevailing among both gender, and with a greater ubiquity among the geriatric population. The role of dopamine hyperactivity in the fronto-parietal-temporal region was implicated, with the anatomical mapping of the ventromedial prefrontal cortex (vmPFC), cingulate gyrus (CG), and amygdala involvement in the context of the disease's neurobiology. The etiology of pathological jealousy includes major psychiatric disorders, i.e. delusional disorder, schizophrenia, mood disorder, organic brain syndrome, and among others, the drug-induced psychosis. The role of relationship issues and psychodynamic perspective, i.e. psychological conflicts with dependence on a romantic partner, and low self-esteem are involved. Pathological jealousy inherits high-risk forensic psychiatry entanglement, which may warrant intensive intervention, including hospital admission and antipsychotic treatment. Treatment options include an early recognition, managing underlying neuropsychiatric disorders, psycho education, cognitive psychotherapy, and choosing an effective psychopharmacological agent. The management strategy may also resort to a geographical intervention, i.e. separation between both persons to complement the biological treatment.
  15. The Phosphodiasterase 5-Inhibitors (PDE-5i) for Erectile Dysfunction (ED): A Therapeutic Challenge For Psychiatrists
    Koon CS, Sidi H, Kumar J, Xi OW, Das S, Hatta MH, et al.
    Curr Drug Targets, 2018;19(12):1366-1377.
    PMID: 28215172 DOI: 10.2174/1389450118666170215164747
    Erectile function (EF) is a prerequisite for satisfactory sexual intercourse (SI) and central to male sexual functioning. Satisfactory SI eventually initiates orgasm - a biopsychophysiological state of euphoria - leading to a sense of bliss, enjoyment and positive mental well being. For a psychiatrist, treating ED is self-propelled to harmonize these pleasurable experiences alongside with encouragement of physical wellness and sensuality. Hence, the role of PDE-5i is pivotal in this context and constitutes a therapeutic challenge. PDE-5i work via the dopaminergic-oxytocin-nitric oxide pathway by increasing the availability of endothelial's guanosine monophosphate (GMP), immediately causing relaxation of the penile smooth muscle and an erection. The PDE-5i, like sildenafil, vardenafil and tadalafil, are effective in the treatment of ED with some benefits/ flexibilities and disadvantages compared to other treatment modalities. Prescribed PDE-5i exclusively improve EF, fostering male's self-confidence and self-esteem. Treatment failures are associated with factors such as absent (or insufficient) sexual stimulation, psychosexual conflicts and the co-existence of medical disorders. Managing ED requires dealing with underlying medical diseases, addressing other co-morbid sexual dysfunctions like premature ejaculation (PE), and educating the patient on healthy life-styles. Furthermore, by dealing with interpersonal dynamics within the couple and embracing adequate lifestyles (managing stress and revising one's sexual scripts), PDE-5i treatment benefits may be enhanced. In this review, we propose a holistic conceptual framework approach for psychiatric management of patients with ED.
  16. Hypersexuality As a Neuropsychiatric Disorder: The Neurobiology and Treatment Options
    Asiff M, Sidi H, Masiran R, Kumar J, Das S, Hatta NH, et al.
    Curr Drug Targets, 2018;19(12):1391-1401.
    PMID: 28325146 DOI: 10.2174/1389450118666170321144931
    Hypersexuality refers to abnormally increased or extreme involvement in any sexual activity. It is clinically challenging, presents trans-diagnostically and there is extensive medical literature addressing the nosology, pathogenesis and neuropsychiatric aspects in this clinical syndrome. Classification includes deviant behaviours, diagnosable entities related to impulsivity, and obsessional phenomena. Some clinicians view an increase in sexual desire as 'normal' i.e. psychodynamic theorists consider it as egodefensive at times alleviating unconscious anxiety rooted in intrapsychic conflicts. We highlight hypersexuality as multi-dimensional involving an increase in sexual activity that is associated with distress and functional impairment. The aetiology of hypersexuality is multi-factorial with differential diagnoses that include major psychiatric disorders (e.g. bipolar disorder), adverse effects of treatments (e.g. levodopatreatment), substance-induced disorders (e.g. amphetamine substance use), neuropathological disorders (e.g. frontal lobe syndrome), among others. Numerous neurotransmitters are implicated in its pathogenesis, with dopamine and noradrenaline playing a crucial role in the neural reward pathways and emotionally- regulated limbic system neural circuits. The management of hypersexuality is determined by the principle of de causa effectu evanescent, if the causes are treated, the effect may disappear. We aim to review the role of pharmacological agents causing hypersexuality and centrally acting agents treating the associated underlying medical conditions. Bio-psycho-social determinants are pivotal in embracing the understanding and guiding management of this complex and multi-determined clinical syndrome.

    The workers and employees in various institutions are subjected to different shifts and work schedules. The employees work not only at daytime but also during odd hours at night. The biological clock of an individual is often altered during night shifts. This affects the psychosocial well-being and circadian nutritional intake of the worker. Disturbance in circadian rhythm results in the development of metabolic disorders such as hypertension, dyslipidemia, dysglycemia, and abdominal obesity. In the present review, we discuss the nature of shift work, sleep/wake cycle of an individual, chrononutrition, dietary habits, and meal changes with regard to timing and frequency, related to shift work. We also discuss the relationship between nutritional intake and psychosocial well-being among shift workers. The review may be beneficial for prevention of metabolic disorders and maintaining sound psychological condition in shift workers.
  18. Fulltext Intraoperative cerebral oximetry in open heart surgeries reduced postoperative complications: A retrospective study

    Cardiothoracic surgeries are life-saving procedures but often it results in various complications. Intraoperative cerebral oximetry monitoring used to detect regional cerebral oxygen saturation (rScO2) is a non-invasive method that provides prognostic importance in cardiac surgery. The main aim of the present study was to evaluate the association of intraoperative cerebral oxygen monitoring during cardiac surgery on postoperative complications. This was a case-controlled retrospective study conducted on adult patients, who underwent open-heart surgery in National Heart Institute, Malaysia. The case group comprised patients on protocolized cerebral oximetry monitoring. They were treated using a standardized algorithm to maintain rScO2 not lower than 20% of baseline rScO2. The control group comprised patients with matched demographic background, preoperative risk factors, and type of surgical procedures. Propensity score stratification was utilized to contend with selection bias. Retrospective analysis was performed on 240 patients (case group) while comparing it to 407 patients (control group). The non-availability of cerebral oximetry monitoring during surgery was the prominent predictor for all outcome of complications; stroke (OR: 7.66), renal failure needing dialysis (OR: 5.12) and mortality (OR: 20.51). Postoperative complications revealed that there were significant differences for risk of mortality (p<0.001, OR = 20.51), renal failure that required dialysis (p<0.001, OR = 5.12) and stroke (p <0.05, OR = 7.66). Protocolized cerebral oximetry monitoring during cardiothoracic surgeries was found to be associated with lower incidence of stroke, renal failure requiring dialysis and mortality rate.

    Indian J Med Sci, 2009 Oct;63(10):445-54.
    PMID: 19901483
    BACKGROUND: There is a paucity of literature on validated outcome measurement tools for evaluation of neck pain and related disability in the Asian context.

    AIM: The main aim of the present study was to design a new tool called neck pain functional limitation scale (NPFLS) for measuring disability related to neck pain and observe its reliability, concurrent validity and criterion validity.

    SETTING AND DESIGN: This study was performed at the institutional hospital.

    MATERIALS AND METHODS: A total of 157 subjects (neck pain group) and 25 control subjects (control group) without neck pain were recruited for this study. NPFLS was framed as a new tool for this study, which consisted of 5 domains - pain intensity, activities of daily living, social activities, functional activities and psychological factors. Neck Bournemouth questionnaire (NBQ) was used as a gold standard to measure the concurrent validity and criterion validity of the NPFLS.

    STATISTICAL ANALYSIS: Criterion validity and concurrent validity between the neck Bournemouth questionnaire (NBQ) and NPFLS scores were tested statistically using Mann-Whitney U test and Spearman correlation test. The reliability was tested by examining the internal consistency to calculate the Cronbach's alpha value for each item in NPFLS.

    RESULTS: No significant difference between NPFLS and NBQ was observed using Mann-Whitney U Test, with P value greater than 0.05 (P= 0.557). Besides that, NPFLS had a high concurrent validity (r= 0.916) and good internal consistency with high Cronbach's alpha value of (r= 0.948), which demonstrated strong correlation between the items of NPFLS and NBQ.

    BACKGROUND AND AIMS:
    Diabetic foot ulcer is one of the major health problems that accounts for increased morbidity among the diabetic patients. Having good knowledge, good attitude and practice of managing the foot prevents the impending chronic co-morbidities of the disease.

    MATERIALS AND METHODS:
    This cross-sectional study was performed to assess the knowledge, attitude and practice on foot care among the newly diagnosed diabetic type 2 patients with low education and socio economic background. This study was conducted in one of the out patient clinics in a tertiary hospital. A set of questionnaire adopted from The Michigan Diabetes Research and Training Center (MDRTC), was used to assess 109 respondents based on their knowledge of diabetes mellitus, practice and attitude towards the condition and care of the feet.

    RESULTS:
    The overall finding on knowledge, practice and attitude had shown unsatisfactory result. There was no relationship between the knowledge, practice and attitude with care of the feet. Only 20 (18.3%) respondents had a high score on knowledge, 31 (28.4%) had practiced good habits and 5 (4.6%) showed positive attitude towards care of the feet. However, there was significant finding on the level of education and the knowledge of foot care (p=0.01);

    CONCLUSION:
    Strategies should be developed to overcome the longterm complications. As for the Muslim patients, ablution, the ritual practice of washing and cleaning both feet prior to the prayers may be a possible means of checking the feet for any diabetic foot complication.
