Abstract
Medical students are one of the socially active, reliable, and persuading population of information, prevention and control, and incentive of vaccination to stop the current pandemic situation. Consequently, knowing the status of medical students' knowledge, about symptoms, and transmission of disease, prevention of COVID-19 and their attitudes towards a vaccine is important. This multi-center cross-sectional descriptive study was one of the first ones in Bangladesh among the undergraduate medical students who completed pathology, microbiology, and pharmacology. The study was conducted from March to April 2021, using a convenience sampling method in twelve government and non-government medical colleges. Among 1132 who completed the questionnaire, and 15 students from different centers were excluded from the pre-testing and face validation. The age of the 1117 respondents were 22 to 23 years, of which the majority of the respondents were female 749 (67.0%), and 368 (33.0%) were male. Almost all participants had correct knowledge (84.1%) about the symptoms of COVID-19. But 59.2% had wrong knowledge about transmission of disease by an afebrile person. Above 60.0 % of the participants have worn a facial mask when contacting people, refrained from shaking hands, washed hands, avoided people with signs and symptoms suggestive of COVID-19, and avoided crowded places as a practice of prevention. 37.6% of medical students showed positive attitudes about the participation of management of a COVID-19 patient. Most of the participants' decided to have a vaccine depending on its availability. But 31.5% had trust in natural immunity rather than vaccination. Most undergraduate Medical college students understood the basic information, possessed a positive attitude, and presented good practice towards the COVID-19 and vaccination. They play a crucial role in motivation and acceptance of vaccines among the general citizen to fight back against the pandemic in the country with limited resources.

Efficacy of Intravenous Ketamine in Adolescent Treatment-Resistant Depression: A Randomized Midazolam-Controlled Trial. FOCUS (AMERICAN PSYCHIATRIC PUBLISHING) 2022; 20:241-251. [PMID: 37153136 PMCID: PMC10153503 DOI: 10.1176/appi.focus.22020004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/06/2020] [Revised: 09/22/2020] [Accepted: 11/25/2020] [Indexed: 05/09/2023]
Abstract
Objective Adolescent depression is prevalent and is associated with significant morbidity and mortality. Although intravenous ketamine has shown efficacy in adult treatment-resistant depression, its efficacy in pediatric populations is unknown. The authors conducted an active-placebo-controlled study of ketamine's safety and efficacy in adolescents. Methods In this proof-of-concept randomized, double-blind, single-dose crossover clinical trial, 17 adolescents (ages 13-17) with a diagnosis of major depressive disorder received a single intravenous infusion of either ketamine (0.5 mg/kg over 40 minutes) or midazolam (0.045 mg/kg over 40 minutes), and the alternate compound 2 weeks later. All participants had previously tried at least one antidepressant medication and met the severity criterion of a score >40 on the Children's Depression Rating Scale-Revised. The primary outcome measure was score on the Montgomery-Åsberg Depression Rating Scale (MADRS) 24 hours after treatment. Results A single ketamine infusion significantly reduced depressive symptoms 24 hours after infusion compared with midazolam (MADRS score: midazolam, mean=24.13, SD=12.08, 95% CI=18.21, 30.04; ketamine, mean=15.44, SD=10.07, 95% CI=10.51, 20.37; mean difference=-8.69, SD=15.08, 95% CI=-16.72, -0.65, df=15; effect size=0.78). In secondary analyses, the treatment gains associated with ketamine appeared to remain 14 days after treatment, the latest time point assessed, as measured by the MADRS (but not as measured by the Children's Depression Rating Scale-Revised). A significantly greater proportion of participants experienced a response to ketamine during the first 3 days following infusion as compared with midazolam (76% and 35%, respectively). Ketamine was associated with transient, self-limited dissociative symptoms that affected participant blinding, but there were no serious adverse events. Conclusions In this first randomized placebo-controlled clinical trial of intravenous ketamine in adolescents with depression, the findings suggest that it is well tolerated acutely and has significant short-term (2-week) efficacy in reducing depressive symptoms compared with an active placebo.Reprinted from Am J Psychiatry 2021; 178:352-362 with permission from American Psychiatric Association Publishing.

Abstract
Background: Placebo response has been identified as an important factor influencing the success of adult antidepressant trials, yet little research of placebo response has been conducted in pediatric populations. Understanding disorder-specific and transdiagnostic predictors of pediatric placebo response is important in designing successful child psychopharmacological trials. Methods: A PubMed search was conducted for all pediatric antidepressant randomized controlled trials treating depression, anxiety, or obsessive-compulsive disorder (OCD). A random-effects model was utilized to examine the magnitude of placebo symptom improvement using standardized mean difference (SMD) and placebo response rates. Stratified subgroup analysis was performed by diagnostic indication. Meta-regression was utilized to search possible correlates of placebo symptom improvement and placebo response rate. Results: Thirty antidepressant trials involving 2911 participants receiving placebo were included in this meta-analysis. Magnitude of placebo improvement and placebo response rates varied significantly across disorders; being greater in depression (SMD = 1.44, 95% confidence interval [CI]: 1.18 to 1.71) than anxiety disorders (SMD = 1.09, 95% CI: 0.77 to 1.41) and the lowest in OCD (SMD = 0.71, 95% CI: 0.32 to 1.12). Different predictors were associated with placebo response in different indications. Conclusions: Both the magnitude and predictors of placebo response in pediatric depression trials do not replicate across anxiety and OCD. Based on our results, across disorders, minimizing the number of sites might significantly reduce placebo improvement. In addition to these, we could potentially decrease the placebo response in depression trials by increasing the number of subjects enrolled per study site, minimizing the number of study visits and conducting the studies in the United States. Further research is needed into the predictors of placebo response in pediatric anxiety and OCD.

Abstract
The present study was designed to evaluate the strength of association of raised plasma homocysteine concentration as a risk factor for coronary heart disease independent of conventional risk factor. It was a case control study conducted at Punjab Institute of Cardiology Lahore. A total of 210 subjects aged 25 to 60 years comprising of 105 newly admitted patients of CHD as cases and 105 age and sex matched healthy individuals with no history of CHD as control were recruited for the study. Fasting blood samples were obtained from cases and controls. Plasma homocysteine was analyzed by fluorescence polarization immunoassay (FPIA) method on automated immunoassay analyzer (Abbott IMX). Total cholesterol, triglyceride and HDL cholesterol were analyzed using calorimetric kit methods. The concentration of LDL cholesterol was calculated using Friedewald formula. The patients were also assessed for traditional risk factors such as age, sex, family history of CVD, hypertension, smoking and physical activity, and were compared with control subjects. The collected data was entered in SPSS version 24 for analysis and interpretation.The mean age in controls and experimental groups were 43.00± 8.42 years and 44.72± 8.59 years with statistically same distribution (p- value= 0.144). The mean plasma homocysteine for cases was 22.33± 9.22 µmol/L where as it was 12.59±3.73 µmol/L in control group. Highly significant difference was seen between the mean plasma level of homocysteine in cases and controls (p˂0.001).Simple logistic regression indicates a strong association of coronary heart disease with hyperhomocysteinemia (OR 7.45), which remained significantly associated with coronary heart disease by multivariate logistic regression (OR 7.10, 95%C1 3.12-12.83, p=0.000). The present study concludes that elevated levels of Plasma homocysteine is an independent risk factor for coronary heart disease independent of conventional risk factors and can be used as an indicator for predicting the future possibility for the onset of CVD.

Abstract
In this issue, we read with interest Research Review: Developmental origins of depression - a systematic review and meta-analysis (Su et al., 2021). Su et al. (2021) conducted a systematic review and meta-analysis examining prenatal, perinatal and postnatal exposures and their association with depression in offspring. Su et al. (2021) evaluated twenty-eight potential exposures and determined that 12 were associated with increased risk of depression in the offspring. These risk factors included low birth weight, premature birth, being small gestational age, maternal education, socioeconomic status, parental age, parental smoking, maternal stress, maternal anxiety and prenatal depression (Su et al., 2021). Strikingly, each of these developmental risk factors for depression in the offspring is known to be associated with poverty.

Abstract
Healthcare professionals are the crucial and influencing source of information for vaccines and their communication among patients and communities that can accelerate successful vaccination in a country. This cross-sectional study was one of the first and foremost ones in Bangladesh to observe the basic perception and attitudes towards vaccination against COVID-19 among the healthcare workers (HCWs) - doctors, interns, nurses, ward boys, cleaners, and medical technologists of major COVID-dedicated hospitals. The cross-sectional questionnaire-based study was conducted in February 2021 among 550 HCWs to assess the perception and attitude towards vaccination against COVID-19. The study participants were targeted as the priority group for COVID-19 vaccination, working in two major COVID-dedicated hospitals, Holy Family Red Crescent Medical College Hospital (HF-center), and Sheikh Russel National Gastro-liver Institute and Hospital (SR-center) in Dhaka, Bangladesh during the pandemic. The questionnaire was structured with a three-point scale of responses from 'true', 'false', and 'do not know'. The responses were calculated on point-score as +1 for the correct response, -1 for the wrong response, and 0 for 'do not know' with an overall highest and the lowest possible score of +5 to -5. Absolute (n) and relative frequencies (%) were presented for qualitative variables, while quantitative variables were presented as mean (± standard deviation). Chi-square test was done for univariate analysis of qualitative variables and Student's t-test for quantitative variables. With the 95.27% response rate, including 204 males and 320 were female and the male: female ratio was 1: 1.56. The majority of the participants were doctors (45.8%) followed by nurses (27.9%), and MLSS (26.3%) respectively. The respondents were between 18 to 64 years of age with a mean of 36.17±10.94 years. Most of the respondents (95.99%) responded correctly about the cost-free availability of a vaccine against COVID-19 in the country, 87.40% preferred vaccination as safe and effective. Again 29.77% HCWs think the vaccine might not be safe or effective due to emergency authorization. Only 38.93% of respondents could respond correctly about the necessity of vaccines for children, 31.10% think the vaccination was not required instead of natural immunity. The positive perception and attitude of the frontline HCWs in COVID-dedicated hospitals in Bangladesh are crucial which will positively influence motivation and wide acceptance among the general population for the attainment of the nationwide vaccination program, and adopt effective strategic modification to minimize the gaps for a low-middle income country like Bangladesh with its resource constrain.

Abstract
Since the first detection of a cluster of COVID-19 patients in China in late 2019, it becomes a global concern due to its transmissibility and ability to progress patients in severe respiratory failure and acute respiratory distress syndrome, which need intensive care unit support for a long time. We observed the repurposing use of remdesivir and favipiravir whether considered as a therapeutic option or not through survival rate and changes in biomarker during 10-day treatment stay in ICU.
The retrospective observational study in a tertiary care hospital dedicated to COVID-19 at Dhaka, Bangladesh was done at the peak of COVID-19 pandemic in Bangladesh. The mortality rate, length of ICU stays and eight prognostic biomarkers of patients treated with remdesivir and favipiravir was observed as one of the first ever reported experience in Bangladesh.
Among the critically ill patients in ICU, 26 (44.8%) died and 32 (55.2%) were cured during the study period and highest mean duration of stay in ICU was observed (14.33 days and 18.13 days) in FPV-treated patients. Mean of means for all biomarkers CRP (26.0) and d-Dimer (2.64) was recorded higher in favipiravir treated patients in death cases, but NLR, d-NLR, platelet, PLR was much higher in remdesivir treated patient of both death and improved cases. Though overall outcome variables between death and improved cases were not statistically significant (p<0.39)
The severity of disease progression in critically ill COVID-19 patients in ICU depends on comorbidities and hyper-responsive inflammatory or immunological biomarkers to predict. Though the emergency use authorization and repurposing use of different antivirals are still on trial, but remdesivir and favipiravir revealed not much hope in improving prognostic biomarkers, survival rate and disease progression at the peak of pandemic in Bangladesh.

Meta-analysis: Pharmacologic Treatment of Restricted and Repetitive Behaviors in Autism Spectrum Disorders. J Am Acad Child Adolesc Psychiatry 2021; 60:35-45.

Abstract
OBJECTIVE To examine the efficacy of pharmacological treatments for restricted and repetitive behaviors (RRB) in autism spectrum disorders (ASD). METHOD We searched PubMed, Embase, and CENTRAL to identify all double-blind, randomized, placebo-controlled trials that examined the efficacy of pharmacological agents in the treatment of ASD and measured RRB as an outcome. Our primary outcome was the standardized mean difference in rating scales of RRB. RESULTS We identified 64 randomized, placebo-controlled trials involving 3,499 participants with ASD. Antipsychotics significantly improved RRB outcomes compared to placebo (standardized mean difference [SMD] = 0.28, 95% CIs = 0.08-0.49), z = 2.77, p = .01) demonstrating a small effect size. Larger significant positive effects on RRB in ASD were seen in individual studies with fluvoxamine, buspirone, bumetanide, divalproex, guanfacine, and folinic acid that have not been replicated. Other frequently studied pharmacological treatments in ASD including oxytocin, omega-3 fatty acids, selective serotonin reuptake inhibitors (SSRI), and methylphenidate did not demonstrate significant benefit in reducing RRB compared to placebo (oxytocin: SMD = 0.23, 95% CI = -0.01 to 0.47, z = 1.85, p = .06; omega-3 fatty acids: SMD = 0.19, 95% CI = -0.05 to 0.43, z = 1.54, p = .12; SSRI: SMD = 0.09, 95% CI = -0.21 to 0.39, z = 0.60, p = .56; methylphenidate: SMD = 0.18, 95% CI = -0.11 to 0.46, z = 1.23, p = .22). CONCLUSION The results of the present meta-analysis suggest that currently available pharmacological agents have at best only a modest benefit for the treatment of RRB in ASD, with the most evidence supporting antipsychotic medications. Additional randomized controlled trials with standardized study designs and consistent and specific assessment tools for RRB are needed to further understand how we can best help ameliorate these behaviors in individuals with ASD.

Abstract
Abstract
Introduction
Prior to the utilization of continuous flow devices in 2010, Gastrointestinal (GI) bleeding was a common adverse event related to LVADs.
Background
Given the drastic increase in the use of new LVADs with continuous flow (CF), we sought to determine if CF-LVADs are associated with an increased number of GI bleeds and higher mortality.
Methods
We analysed the data from a national inpatient sample database using the International Classification of Disease (ICD)-9 procedure code for LVAD use in end-stage heart failure among patients 18 years or older. Included were 2,359 patients with a mean age of 55±13.7 years and 77% males and 59% Caucasians.
Results
The Incidence of GI bleed from 2010 to 2014 was 7.46%. There was no significant yearly change in the incidence over five years (p=0.793). After controlling for age, sex, and length of stay (LOS), hierarchical multivariate logistic regression revealed that significant predictors of GI bleed were acute kidney injury (AOR=1.87, 95% CI: 1.26, 2.80), peripheral vascular disease (AOR=1.77, 95% CI: 1.02, 2.94), body mass index ≥25 (AOR=0.46, 95% CI: 0.22, 0.87), hemiplegia and paraplegia (AOR=3.01, 95% CI: 1.17, 7.05), moderate or severe liver disease (AOR=2.40, 95% CI: 0.97, 5.34), peptic ulcer disease (PUD) (AOR=18.13, 95% CI: 7.86, 42.38), surgical aortic valve replacement (AOR=2.46, 95% CI: 1.12, 5.15), and venous thromboembolism (AOR=2.58, 95% CI: 1.57, 4.15).
Conclusion
Earlier studies showed an increase in the rate of GI bleed in CF-LVADs when compared to pulsatile flow devices. However, our study has indicated that CF-LVADs display no improvement in rates of GI bleed over five years, but that there was an increased likelihood of mortality in patients with GI bleed. These findings pose further questions in regard to considering newer device designs and improved patient selection criteria.

Systematic review on current antiviral therapy in COVID-19 pandemic. THE MEDICAL JOURNAL OF MALAYSIA 2020; 75:710-716. [PMID: 33219182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/11/2023]
Abstract
INTRODUCTION Currently, there are several attempts to find an effective antiviral drugs against the COVID-19. Although majority of the COVID-19 patients have mild to moderate clinical events, up to 5-10% may have severe, life threatening events that urgently require effective drugs. The purpose of this systematic review is to evaluate the effectiveness of antiviral therapies in the treatment of COVID-19. METHODS An extensive search was performed in PubMed, EMBASE, Cochrane Library for randomised controlled trials (RCTs), prospective case series studies that evaluated therapies COVID-19. The outcomes searched for were mortality, recovery rate, length of hospital stay and clinical improvement from January to May 15, 2020. Independent reviewers searched, identified, screened, and related studies were included. RESULTS Total of five RCTs on 439 patients and seventeen case series involving 1656 patients were found in the specified review period that reported the use of Lopinavir, Ritonavir, Remdesivir. Oseltamivir, Ribavirin in patients with COVID-19; but none of which showed efficacy of antiviral therapy. Such current findings impede researchers from recommending an appropriate and effective antiviral therapy against COVID-19, making it a serious concern for the global community. DISCUSSION In the present pandemic and any future epidemics, all the related authorities should pursue many more RCTs, cohort and case series for a prospective outcome in the management and treatment guidelines.

Abstract
Stroke is one of the commonest causes of mortality among the world. Hemorrhagic stroke accounts nearly 15% of all the strokes. Different risk factors have been identified, of them hypertension, anti-coagulation therapy and previous history of ischemic strokes are significant. Regarding the genetic causes of intracerebral hemorrhage (ICH) monogenic causes play a small role. It was found that Apolipoprotein E (APOE) gene has a strong association with ICH. This is a 299 amino acids long protein located in chromosome 19. APOE has three alleles, they are epsilon 2, 3 and 4. Total 10 meta-analysis were reviewed in this article which involved 52,705 participants. When looking for the association, ∈2 and ∈4 showed positive and ∈3 showed negative association with ICH. Association of ∈4 (OR mean 1.77) was stronger than that of ∈2 (OR mean 1.71).

Abstract
BACKGROUND Trichotillomania (TTM) is a difficult-to-treat psychiatric condition with no first-line medications approved by the Food and Drug Administration. Individuals with TTM often feel that clinicians know little about this disorder. Here, we present an updated meta-analysis of randomized controlled trials (RCTs) examining treatments for TTM. METHODS Pubmed, PsychINFO, Embase, and CENTRAL were searched with the terms "Trichotillomania OR Hair Pulling Disorder" to identify randomized controlled clinical trials evaluating treatments for TTM. RESULTS Twenty-four trials involving 26 comparisons and 857 participants were included in this meta-analysis. Behavioral therapy with habit-reversal training components (BT-HRT) demonstrated a large benefit compared to control conditions (standardized mean difference [SMD] [95% CI] = -1.22 [-1.71, -0.73], p < .0001) for improving TTM symptoms. Clomipramine (SMD [95% CI] = -0.71 [-1.38, -0.05], p = .036), N-acetylcysteine (SMD [95% CI] = -0.75 [-1.36, -0.13], p = .017) and olanzapine (SMD [95% CI] = -0.94 [-1.77, -0.12], p = .025) demonstrated significant benefits compared to placebo in RCTs. CONCLUSIONS BT-HRT has demonstrated the largest treatment effects and has the strongest evidence base for reducing TTM symptoms. In contrast, several pharmacological agents have demonstrated efficacy in single randomized clinical trials that would benefit from replication. Additional trials are needed to identify other effective medications for TTM and determine the relative efficacy of available agents.

Abstract
The sudden outbreak of a novel coronavirus in 2019 in Wuhan, China, that rapidly provoked a global concern, marked as the third attack of corona virus in the human society that affected the global healthcare system as well as the global economy. Until and unless an effective vaccine is discovered against the virus, the pharmacological intervention by different antivirals is in the run for remedy. The aim of this systematic review was to evaluate the role of favipiravir along with its safety and efficacy for the patients who are suffering from severe acute respiratory distress syndrome due to CoronaVirus-2 (SARS-CoV-2) as re-purposeful use. We searched PubMed, EMBASE for randomized controlled trials (RCTs), cilicaltrial.com for registered on going trails to evaluate the pros and cons of using favipiravir in COVID-19. After vigorous searching, screening and sorting of 314 articles for completed and published scientific evidences in electronic database, there were only 2 completed and published randomized control trials (RCT) and 17 ongoing or unpublished trials found until June 2020. The main outcome measures were viral clearance, clinical improvement and adverse events reported and published on 147 patients infected with SARS-CoV2. The 2 completed RCTs showed significantly better treatment effects on disease progression, viral clearance, improved the latency to relief for pyrexia and cough on favipiravir treated patients. Adverse effects caused Favipiravir are mild and manageable. Although 9 more RCTs and cohort studies are supposed to be completed by this time that may unveil some evidence for use of anti-RNA-viral drug favipiravir against influenza or Ebola to re-purposing against COVID-19 as adopted in different treatment guidelines.

Abstract
The rapid progression of corona virus disease in 2019 (COVID-19) pandemic has become an unprecedented global concern. This systemic review aimed at evaluating the available evidence on efficacy, safety to identify any promising role for compassionate use of remdesivir in patient suffered for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) as re-purposeful use. We searched PubMed, EMBASE, Cochrane Library for randomized controlled trials (RCTs), prospective case series studies and case reports that evaluated use of remdesivir in COVID-19. The outcomes were mortality, recovery rate, length of hospital stay and clinical outcome. Though the drug remdesivir (RDV) is not approved by the FDA, still the "Emergency Use Authorization" (EUA) for compassionate use in severe cases is endorsed. After vigorous searching, screening and sorting of completed and published scientific evidences in electronic database, there were only 2 randomized control trial (RCT), 2 uncontrolled trials found until April 2020. We also included 3 published case reports to analyze the validity use of RDV because of the scarcity of evidence based reports. Remdesivir was thought to be one of the promising options for treating the patients of COVID-19 based on few laboratory experiments and reports from some compassionate use and case reports. The safety and efficacy of this drug in COVID-19 cases require high-quality evidence from well-designed and adequately-powered clinical trials with proper sample size for precise decision.

Abstract
Serotonin reuptake inhibitors and benzodiazepines are evidence-based pharmacological treatments for Anxiety Disorders targeting serotonin and GABAergic systems, respectively. Although clearly effective, these medications fail to improve anxiety symptoms in a significant proportion of patients. New insights into the glutamate system have directed attention toward drugs that modulate glutamate as potential alternative treatments for anxiety disorders. Here we summarize the current understanding of the potential role of glutamate neurotransmission in anxiety disorders and highlight specific glutamate receptors that are potential targets for novel anxiety disorder treatments. We also review clinical trials of medications targeting the glutamate system in DSM-5 anxiety disorders. Understanding the role of the glutamate system in the pathophysiology of anxiety disorder may aid in developing novel pharmacological agents that are effective in treating anxiety disorders.

Trim the fat: the role of omega-3 fatty acids in psychopharmacology. Ther Adv Psychopharmacol 2019; 9:2045125319869791. [PMID: 31489174 PMCID: PMC6713969 DOI: 10.1177/2045125319869791] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Accepted: 07/22/2019] [Indexed: 12/21/2022] Open
Abstract
The American Psychiatric Association (APA) currently recommends the use of omega-3 fatty acid supplementation for depressive disorders, impulse-control disorders, and psychotic disorders in treatment guidelines. This review examines the evidence for efficacy of omega-3 fatty acids in depressive disorders, bipolar disorder, anxiety disorders, post-traumatic stress disorder (PTSD), and psychosis. Meta-analysis of randomized-controlled trials of omega-3 fatty acids for depression are inconclusive, with strong evidence of publication bias, sizable heterogeneity between included studies, and substantial methodological shortcomings in included trials. The large amount of heterogeneity in findings of RCTs of omega-3 fatty acids for unipolar depression is likely attributable to highly heterogeneous sample populations that are given different omega-3 supplements [which differ widely in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) content, ratio, and dosage] as either adjunctive or monotherapy of other existing treatments, and then measure several different outcomes of depression symptomatology with likely incomplete blinding. Evidence of efficacy of omega-3 supplementation in treating psychosis, PTSD, anxiety, and bipolar mania is minimal. The current guidelines recommending the use of omega-3 fatty acids in adulthood psychiatric conditions should be revisited, especially given several recent negative studies examining the effects of omega-3 fatty acids for cardiovascular disease. Recommending likely ineffective treatment to patients, no matter how benign the side-effect profile, has opportunity cost (e.g. other more effective medications or therapies not being utilized) and likely affects patient compliance with other evidence-based treatments.

Abstract
BACKGROUND We aimed to examine the efficacy of selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs) for anxiety disorders examining overall symptom improvement, likelihood of treatment response, time course of treatment response, individual pharmacological agent, diagnostic indication dose, and tolerability. METHODS We searched PubMed and Cochrane Central Register of Controlled Trials. We included randomized placebo-controlled clinical trials of SSRIs/SNRIs in adult patients with anxiety disorders that provided data at three or more time points. Extracted data included trial duration, weekly/biweekly anxiety scores for 12 weeks. RESULTS Meta-analysis included 57 trials (N = 16,056). A linear mixed model analysis based on weekly outcome data suggested that for SNRI a logarithmic model offered the best fit compared to placebo (indicating the greatest incremental improvement from baseline occurred early in treatment); whereas for SSRI a linear model provided the best fit (indicating a similar improvement over the duration of the acute treatment phase). There were no significant differences in efficacy between pharmacological agents within each class or when comparing SSRIs to SNRIs. The greatest treatment benefits were observed for social anxiety disorder for both medication classes. Higher doses of SSRIs, but not SNRIs, were associated with significantly greater symptom improvement and likelihood of treatment response. For both medical classes, higher doses were associated with an increased likelihood of dropout due to side effects. CONCLUSIONS SSRIs and SNRIs are effective in treating anxiety disorders. Higher doses of SSRIs within the therapeutic range are associated with greater treatment benefit, whereas higher doses of SNRIs are not.

Abstract
Smad ubiquitin regulatory factors (SMURFS) belong to the HECT- family of E3 ubiquitin ligases. This family has two members, SMURF1 and SMURF2. SMURFs have emerged as well studied negative regulators of TGF induced intracellular signaling. However, increasingly it is being realized that SMURFs tactfully modulate an array of proteins in different cancers. This review sets spotlight on how SMURF1 and SMURF2 communicate with effectors of different signaling pathways during the multistep progression to cancer. We also summarize how microRNAs (miRNAs) effectively control SMURFs in different cancers. Role of SMURFs is context dependent in different cancers and better concepts related to miRNA regulation of SMURFs in different stages and steps of cancer will be helpful in efficient translation of laboratory findings to clinic.

Abstract
INTRODUCTION Robotic surgery provides an alternative option for a minimal access approach. It provides a stable platform with high definition three-dimensional views and improved access, which enhances the capabilities for precise dissection in a narrow surgical field. These distinctive features have made it an attractive option for colorectal surgeons. AIM The aim of this study was to present a standardised technique for single-docking robotic rectal resection and to analyse clinical outcomes of the first 100 robotic rectal procedures performed in a single centre between May 2013 and April 2015. METHOD Prospectively collected data related to 100 consecutive patients who underwent single-docking robotic rectal surgery was analysed for surgical and oncological outcomes. RESULTS Sixty-six patients were male, the median age was 67 years (range-24-92). Eighteen patients had neo-adjuvant chemoradiotherapy whilst 23 patients had BMI >30. Procedures performed included anterior resection (n = 74), abdominoperineal resection (n = 10), completion proctectomy (n = 9), restorative proctectomy with ileal pouch-anal anastomosis (IPAA) (n = 5) and Hartmann's procedure (n = 2). The median operating time was 240 min (range-135-456), and median blood loss was 10 ml (range 0-200). There was no conversion or intra-operative complication. Median length of stay was 7 days (range, 3-48) and readmission rate was 12 %. Thirty-day mortality was zero. Postoperatively, two patients had an anastomotic leak whilst two had small bowel obstruction. The median lymph node harvest was 18 (range, 6-43). CONCLUSION The single-docking robotic technique should be considered as an alternative option for rectal surgery. This approach is safe and feasible and in our study it has demonstrated favourable clinical outcomes.

Abstract
AIMS It is well established that the serotonergic system contributes to the regulation of glucose homeostasis and feeding and therefore it has been presumed to contribute to the biological susceptibility to type 2 diabetes mellitus (T2DM) and body-mass index (BMI). 5-HTTLPR is a serotonin transporter (5-HTT) gene-linked polymorphic region that regulates the transcriptional activity of 5-HTT. Our aim was to investigate the possible association of 5-HTTLPR polymorphism (L and S alleles) in the promoter region of the serotonin transporter gene with T2DM and/or higher BMI in Pakistani population. METHODS In this study, 574 subjects diagnosed with T2DM and 402 unrelated normal controls from the general Pakistani population were genotyped for 5-HTTLPR polymorphism by PCR amplification and agarose gel electrophoresis. The genotyping data (S/S, S/L and L/L) were recorded and analysed statistically using various software and online available tools. RESULTS In the total sample, patients with type 2 diabetes and controls without diabetes, genotypes were distributed according to Hardy-Weinberg equilibrium, and S allele frequency was 61.52% (0.61). There was no statistical association between 5-HTTLPR polymorphism and the development of T2DM in this Pakistani population (p=0.12). CONCLUSIONS No significant statistical association of 5-HTTLPR polymorphism with type 2 diabetes and obesity in Pakistani population shows that 5-HTTLPR polymorphism is not a major factor in determining type 2 diabetes and obesity in Pakistan.

Abstract
Small molecule drugs are the foundation of modern medical practice yet their use is limited by the onset of unexpected and severe adverse events (AEs). Regulatory agencies rely on post-marketing surveillance to monitor safety once drugs are approved for clinical use. Despite advances in pharmacovigilance methods that address issues of confounding bias, clinical data of AEs are inherently noisy. Systems pharmacology– the integration of systems biology and chemical genomics – can illuminate drug mechanisms of action. We hypothesize that these data can improve drug safety surveillance by highlighting drugs with a mechanistic connection to the target phenotype (enriching true positives) and filtering those that do not (depleting false positives). We present an algorithm, the modular assembly of drug safety subnetworks (MADSS), to combine systems pharmacology and pharmacovigilance data and significantly improve drug safety monitoring for four clinically relevant adverse drug reactions.

Abstract
In terms of engineering, clinical understanding and application, device therapy remains in its infancy. In clinical trials, implantable cardiac defibrillators (ICDs) have greatly reduced the rate of sudden death and had a modest impact on mortality in a relatively broad range of patients. They do not generally improve symptoms and may make them worse. Cardiac resynchronisation therapy (CRT) devices have been used more selectively - probably far too selectively - and have shown substantial improvement in symptoms and a large reduction in mortality both by reducing sudden death and death due to heart failure. These effects are not explained solely by improved ventricular function, and the clinical response to therapy has so far not been predicted well by any method of assessing cardiac function or dyssynchrony. Reduction in brady-arrhythmia-triggered sudden death may be an underestimated benefit of biventricular pacing. In recent trials, heart failure patients implanted with a device have had a remarkably low mortality. This forces the clinical community to contemplate universal device use for patients with heart failure, except in those who have irremediable, life-limiting, non-cardiac disease. For most patients this should be CRT or a combination of CRT and an ICD (CRT-D).

Abstract
Human disease caused by enterohemorrhagic E. coli O157:H7 and other serotypes (EHEC) has been associated with bovine fecal contamination of food and the environment. The range of serotypes, low infectious dose, and numerous transmission vehicles for EHEC render development of detection methods for this pathogen complex. In this study, the hemolysin gene (EHEC- hly A) was targeted with oligonucleotides, and probe-target hybrids were amplified using strand displacement amplification (SDA). Amplicons were resolved in the complete reaction mix through changes in the fluorescence polarization (FP) of a fluorescein-labeled detector probe hybridized to the amplicons during amplification. Results combining EHEC- hly A, SDA, and FP were obtained within 35 min of reaction initiation. The test specificity was determined on EHEC strains representing 13 serotypes (49 isolates); and control uropathogenic, commensal, and other organisms (10 isolates). Statistical analysis of results indicated a sensitivity in the reaction vessel to 4.3 bacteria (95% confidence interval), and a specificity for EHEC (n=59) at 100% (P=5.11E-17; i.e. P<<0.05). Detection based on combining EHEC- hly A, SDA, and FP was compatible with water sources directly associated with human infection (drinking and recreational supplies), and bovine drinking trough water representing an environmental matrix linked to the maintenance of an EHEC animal reservoir.
